As shown in FIG. 6, the display screen 15 has a main display area 41 and an item name display area 42. In the display screen 15, the horizontal axis (X axis) is set as the time axis, and the vertical axis (Y axis) is set as the data item arrangement axis. As for the time axis, the left direction is set to the past, and the right direction is set to the present. The main display area 41 displays a plurality of medical data (time series data) for each data item. In the main display area 41, a plurality of medical data (time series data) are arranged along the data arrangement axis. The data items of this example include body temperature, blood pressure (upper), and blood pressure (lower) as measured values of vital signs, blood test leukocytes as sample test values, and image test test data There is an inspection image of CT inspection.

The main display area 41 is provided with horizontal grid lines (corresponding to second grid lines) 46 that divide the main display area 41 in units of displayed data items in the data array axis direction. The horizontal grid lines 46 extend in the horizontal axis (X-axis) direction, and the regions delimited by the horizontal grid lines 46 are a plurality of sub-regions 41A. In each sub-area 41A, medical data (time series data) for each data item is displayed. Each sub-region 41A is a data display row whose longitudinal direction extends in the time axis direction and has a height for displaying each data.

The interval between the horizontal grid lines 46 can be adjusted. By adjusting the interval between the horizontal grid lines 46, the height (width in the vertical axis direction) of each sub-region 41A can be adjusted. For example, the distance between the horizontal grid lines 46 can be changed by designating the horizontal grid lines 46 using the pointer 35 and performing a mouse drag operation. Thereby, the height of each sub-region 41A is adjusted.

In each sub-area 41A, the display form of the medical data (time series data) varies depending on the data item. For example, vital signs data items, such as body temperature, blood pressure (upper), blood pressure (lower), and specimen examination data items, leukocytes, are displayed in the form of a line graph G, respectively. The line graph G is a graph in which the input points P where medical data exist are connected by line segments.

For the inspection image, a thumbnail image TP is displayed on each acquisition date of the inspection image. The thumbnail image TP is, for example, an icon that can be clicked with a mouse, and the main image corresponding to the thumbnail image TP is displayed by the click operation.

Also, for S injection solution, J tablet, and B transfusion, which are data items of medication and injection, a square mark M is displayed at the time of administration. In the data items of medication and injection, if the administration date is continuous, such as J tablet or B infusion, the mark M is displayed on the first day and the last day of the continuous administration period, It is displayed in the form of connecting with line segments. The sub-areas 41A are arranged in the vertical axis (Y-axis) direction, and the vertical axis is the data item arrangement axis on the display screen 15.

In each sub-region 41A where the line graph G is displayed, the height direction corresponds to the fluctuation direction of the data value of the line graph G. In each sub-area 41A, reference numeral 47 indicated by dot hatching is a normal range indicator indicating a range set as a normal range of data values for each data item. For example, in the case of body temperature, a range of 36 ° C. to 37 ° C. is set as a normal range, and a normal range indicator 47 is displayed in the range. The respective normal range indicators 47 are also displayed for blood pressure (upper), blood pressure (lower), and white blood cells.

Further, in the line graph G, when the data value is within the normal range, each input point P is represented by an outline dot in which only the circular outline is not filled, as indicated by the input point P1. When the data value is out of the normal range, it is displayed as a solid dot in which the inside of the circular outline is filled as indicated by the input point P2. Whether the data value is normal by providing the normal range indicator 47 and using the outline dot and the solid dot depending on whether or not the data value is within the normal range for the display form of the input point P. You can easily tell whether or not.

The main display area 41 is provided with vertical grid lines 48 (corresponding to first grid lines) that divide periods in predetermined units in the time axis direction. The vertical grid line 48 extends in the vertical axis (Y-axis) direction. In this example, the period is divided in units of one day by the vertical grid line 48. For this reason, the interval between two adjacent vertical grid lines 48 corresponds to the width of a column of one day. As with the horizontal grid line 46, the interval between the vertical grid lines 48 can be adjusted, and by adjusting the interval between the vertical grid lines 48, the width of the column in a day can be increased or decreased. It is. The method for adjusting the interval between the vertical grid lines 48 can be performed by specifying the vertical grid lines 48 with the pointer 35 and performing a mouse drag operation, as with the horizontal grid lines 46.

The main display area 41 can be scrolled in the horizontal direction (X-axis direction) and the vertical direction (Y-axis direction). A display range of medical data such as a line graph G displayed in the main display area 41 can be changed by a screen scroll operation in the horizontal direction. When the patient's hospitalization period or hospitalization period becomes long, or when the patient repeatedly enters and leaves the hospital, the period for which medical data exists is long. Since the screen size of the display 28A is limited, the entire period of long-term medical data cannot be displayed at once in the main display area 41. In the example shown in FIG. 6, the display range of the main display area 41 is about January of August 2014 in the entire period in which the medical data exists. By the screen scroll operation in the horizontal direction, the display range of the main display area 41 can be changed, for example, from August 2014 to January of July or June.

Also, data items that are not displayed can be displayed by scrolling the screen in the vertical direction. For example, in the example shown in FIG. 6, data items of S injection, J tablet, and B infusion are displayed as data items of medication and injection. If there is data, it can be displayed by scrolling the screen in the vertical direction.

The item name display area 42 is arranged at the left end of the main display area 41. In the item name display area 42, the item name of the medical data displayed in each sub-area 41A is displayed. In the item name display area 42, in addition to item names such as body temperature, blood pressure (upper), blood pressure (lower), white blood cell, CT examination, S injection, etc., each of vital, specimen examination, image examination, medication, injection, etc. The category name to which the data item belongs is also displayed.

The display screen 15 is provided with two time axes, a first time axis 51 and a second time axis 52. The first time axis 51 is provided above the main display area 41, and the second time axis 52 is provided at the upper end in the main display area 41. The second time axis 52 is a time axis representing the display period of the main display area 41. The second time axis 52 has a width in the vertical direction, and displays a number representing a date and a scale provided in units of one day. In FIG. 6, the main display area 41 displays the medical data for January of August 2014. Correspondingly, the second time axis 52 shows the data for about January of August 2014. The date is displayed.

On the other hand, the first time axis 51 can display a display period that is relatively longer than the second time axis 52. In the two-dimensional display mode, the first time axis 51 has a display period that is relatively longer than that of the second time axis 52. In the example of FIG. 6, the display period of the second time axis 52 is about January of August 2014, whereas the display period of the first time axis 51 is from June 2014 to August 2014. It's about March. Similarly to the second time axis 52, the first time axis 51 has a width in the height direction, and a number representing the year and month and a scale for dividing the period by a predetermined interval are displayed.

On the first time axis 51, a presence indicator 51A indicating a period in which medical data exists is displayed. With the presence indicator 51 </ b> A, it is possible to confirm in which period medical data exists within the display period of the first time axis 51. In addition, when an arbitrary time is designated by the pointer 35 on the first time axis 51, medical data at that time can be displayed in the main display area 41. For example, on the first time axis 51, when the June 2014 presence indicator 51A is designated by the pointer 35, the display period displayed in the main display area 41 is changed from August 2014 to June 2014. The

In the main display area 41, reference numeral 53 is a compression indicator that indicates a compression period. In the case of a patient who is not hospitalized but undergoing medical care by going to the hospital, or a patient who repeatedly enters and leaves the hospital, there is a blank period in which no medical data exists. During the blank period in which there is no medical data, only a blank is displayed in the main display area 41, so that only display space is wasted. Therefore, in the main display area 41, for the blank period in which no medical data exists, the display period is compressed in the time axis direction, and the compression mark 53 is displayed there. The compression mark 53 has, for example, a form in which the intervals between the vertical grid lines 48 are narrowed to be dense. In this example, since August 11 to August 17, 2014 is a blank period of medical data, a compression mark 53 is displayed during this blank period. Thereby, the limited main display area 41 can be used effectively.

Further, a display magnification changing unit 54 for changing a magnification for displaying the main display area 41 is provided on the right side of the second time axis 52 and above the item name display area 42. The display magnification changing unit 54 enlarges or reduces the display magnification of the entire main display area 41 by a sliding operation in the plus direction (enlargement direction) or minus direction (reduction direction) of the slider.

It is possible to enlarge and display the line graph G and the thumbnail image TP in the main display area 41 by enlarging the display magnification. On the other hand, the display period is shortened in the horizontal direction, and the number of data items to be displayed is reduced in the vertical direction. On the other hand, when the display magnification is reduced, the line graph G and the thumbnail image TP in the main display area 41 are reduced and displayed, but on the other hand, the display period becomes longer and the number of displayed data items increases.

Further, a display mode switching button 56 is provided above the first time axis 51. The display mode switching button 56 is an operation unit for inputting an operation instruction for switching the display mode of the main display area 41 between the graph display mode and the dot display mode, and is operated by a mouse click operation through the pointer 35.

In the graph display mode, as shown in FIG. 6, the time-series data has a graph form in which the position or display length of the data input point P varies in the data array axis direction according to the value of the input data. Is a display mode for displaying. The form of the graph in this example is a line graph G. The form of the graph may be other than the line graph G, for example, a bar graph in which a plurality of strips whose display lengths in the data arrangement axis direction vary according to the data value are arranged in the time axis direction.

As shown in FIG. 7, the dot display mode is a display mode in which a plurality of input points P of data are displayed in time-series data in the form of a plurality of dots D arranged on a straight line parallel to the time axis. . That is, the plurality of dots D are signs indicating the presence of the input data, similarly to the input point P of the graph G. However, since the plurality of dots D are arranged on a straight line, they are related to the value of the data. The position and display length do not vary in the data array axis direction. For this reason, the height (the height in the data array axis direction) of each sub-area 41A assigned by the data item unit can be reduced. Thereby, in the dot display mode, a large number of data items can be displayed as compared with the graph display mode.

In the dot display mode, the thumbnail image TP displayed in the graph display mode also changes to the display of the image mark PM indicating that the image data exists for the time series data of the CT examination. This is because in the dot display mode, the height of the sub-region 41A is lower than that in the graph display mode, so that time-series data is displayed in accordance with the height.

In the main display area 41, a plurality of cells S partitioned by the vertical grid lines 48 and the horizontal grid lines 46 are provided. In the dot display mode, a dot D is displayed in each cell S.

As shown in FIG. 8 in which a part of the main display area 41 is enlarged, the dot D is similar to the input points P1 and P2 of the line graph G when the data value is within the normal range. As shown in the figure, when the data value is out of the normal range when the outline value is only a circular outline and the inside of the outline is not filled, as shown by a dot D2, the inside of the circular outline Is displayed with solid dots filled.

Thus, by changing the display form of the dot D depending on whether or not the data value is within the normal range, it is possible to easily distinguish whether or not the data value is normal. In the dot display mode, unlike the graph display mode, the position of the dot does not change according to the data value, so that the configuration of changing the display form of the dot D is particularly effective.

Also, as shown in FIG. 8, for the dot D2 whose data value is outside the normal range, a specific numerical value representing the data value is displayed in the vicinity of the dot D2 in the cell S. For example, in the sub-region 41A where the time series data of blood pressure (lower) in the third row from the top is displayed, in the cell S on July 22, there is a specific numerical value of blood pressure (lower) in the vicinity of the dot D2. “101” is displayed. Thereby, it can be easily confirmed how much the data value is out of the normal range.

Also, the number of dots D displayed in the cell changes according to the amount of data input. Specifically, the greater the amount of input data, the greater the number of dots D displayed in the cell. For example, in the blood pressure (lower) sub-region 41A in the third row from the top, the cell S on July 20 has one dot D, whereas the cell S on July 21 has The number of dots D (D2) is two, and the cell S on July 23 has three dots D (D2).

For example, when the blood pressure (lower) is measured once a day and only one piece of measured data is input, the number of dots D is one as shown in the cell S on July 20th. become. On the other hand, when the blood pressure (lower) is measured several times a day and a plurality of measured data is input, the number of dots D is as in the cell S on July 21 and July 23. Become multiple. Thus, the data amount can be easily confirmed by indicating the data amount by the number of dots.

Further, when a plurality of dots D are displayed in one cell S, when the number of dots D is three or more, adjacent dots D are displayed in an overlapping manner. By doing so, even when the number of dots D increases, the column width of the cells S is prevented from expanding in the time axis direction. By not widening the column width of the cells S, the display period of time series data that can be displayed at a time in the main display area 41 can be extended.

In the second time axis 52, a comment mark 57 is displayed on the date when the input comment exists. The comment is, for example, a doctor's finding or a memorandum. An input comment can be displayed by designating the comment mark 57 with the pointer 35 and performing a click operation, or by a mouse-over operation in which the pointer 35 and the comment mark 57 are overlapped.

Also, it may be possible to display comments entered in cell S units instead of date units. In this case, a comment is displayed by clicking the cell S or the dot D in the cell S with the pointer 35 or performing a mouse-over operation for overlapping the pointer 35 with the cell S or the dot D. For example, the input comment is displayed in the form of a tag 58 as shown in the cell S on July 27 in the sub-region 41A in the fourth row from the top. The tag 58 may display the content of data that is not displayed in the cell S in the default state, instead of the comment.

In addition, as shown in FIG. 9, switching between the graph display mode and the dot display mode can be performed in units of items of time series data. As described above, when the display mode switching button 56 is operated, the display modes of all data items displayed in the main display area 41 are switched at once. In addition to this, the display mode may be switched in units of data items. In the example of FIG. 9, only the time series data of white blood cells is displayed in the graph display mode, and other time series data such as body temperature and blood pressure are displayed in the dot display mode.

When the graph display mode is shifted all at once, the height of all the sub areas 41A is increased, and the number of data items displayed in the main display area 41 is reduced. If the display mode can be switched only for any necessary items, for example, while overlooking a large number of data items in the dot display mode, only the items of interest are displayed in the graph display mode and the change over time of the data is confirmed. It is convenient because it can be used.

Such switching of the display mode in item units is performed, for example, by performing a mouse click operation in a state where the sub area 41A is designated by the pointer 35.

Also, as shown in FIG. 10, the size of the cell S can be changed by changing at least one of the interval between the plurality of adjacent vertical grid lines 48 and the interval between the plurality of adjacent horizontal grid lines 46. When the size of the cell S is changed, information displayed in the cell S may be increased.

In the example of FIG. 10, the width of the July 23 column is increased by changing the interval between adjacent vertical grid lines 48. This increases the size of each cell S present in the column. Thereby, for example, in the body temperature and blood pressure cells S in the first to third stages from the top, the interval between the dots D becomes wider from the state where the three dots D overlap and are dense. A numerical value representing a data value is displayed for each dot D. In addition, the measurement time (8:00, 12:00, 12:45) of data corresponding to each dot D is also displayed. In addition, the input comments such as “Examination before operation” and “Confirm CT required” are also displayed. Further, in the CT examination cell S, the thumbnail image TP is enlarged and displayed in a size corresponding to the column width. In the cell S of B infusion, the administration time and dose are displayed.

Hereinafter, the operation of the above configuration will be described with reference to the flowchart shown in FIG. A doctor who treats the patient browses the medical data through the client terminal 12. The doctor activates the viewer software of the client terminal 12, designates the patient ID, and inputs a medical data distribution instruction (S (step) 1010).

Thereby, the distribution request issued from the request issuing unit 34 of the client terminal 12 is transmitted to the medical assistance server 11. When the request reception unit 36 receives a distribution request, the medical assistance server 11 inputs the distribution request to the screen data generation unit 37. The screen data generation unit 37 transmits a medical data acquisition request for the designated patient ID to the server group 13 and acquires medical data (S2010).

In the medical assistance server 11, the screen data generation unit 37 generates screen data of the display screen 15 based on the acquired medical data (S2020). The screen editing unit 38 edits the screen data as necessary, and inputs the screen data to the output control unit 39. The output control unit 39 distributes the screen data to the requesting client terminal 12 via the communication I / F 24 (S2030).

Upon receiving the screen data, the client terminal 12 reproduces, for example, the display screen 15 shown in FIG. 6 on the display 28A based on the screen data received by the GUI control unit 33 (S1020). Since the main display area 41 is displayed in the graph display mode on the display screen 15 shown in FIG. 6, when the main display area 41 is to be displayed in the dot display mode as shown in FIG. The switch button 56 is operated.

When the display mode switching operation (screen editing operation) is performed (Y in S1030), the request issuing unit 34 issues an editing request based on the screen editing request (S1040). The edit request is transmitted to the medical assistance server 11. In the medical assistance server 11, when the request receiving unit 36 receives an editing request, the request receiving unit 36 inputs the editing request to the screen editing unit 38. The screen editing unit 38 performs screen display control for switching the screen data of the display screen 15 from the graph display mode to the dot display mode by screen editing processing (S2040). The edited screen data is distributed to the requesting client terminal 12 by the output control unit 39 (S2050).

Upon receiving the edited screen data, the client terminal 12 reproduces and displays the display screen 15 based on the received screen data (S1050). Thereby, the doctor can browse the main display area 41 in the dot display mode.

In the graph G, the position of the data input point fluctuates in the data array axis direction according to the value of the input data. Therefore, when the fluctuation range of the data value of the graph G is large, the sub-region which is a display row The height of 41A increases. For this reason, when the time series data of all the data items is displayed in the graph display mode, the number of data items that can be displayed at one time in the main display area 41 is reduced and the listability is lowered.

On the other hand, in the dot display mode, the data input points are displayed in the form of a plurality of dots D arranged on a straight line parallel to the time axis. Therefore, unlike the graph G, the input point P does not fluctuate in the data array axis direction, so that the height of the sub-region 41A can be reduced. For this reason, the number of data items that can be displayed in the main display area 41 at a time increases, and the listability improves.

Since time-series data related to medical care is diverse, it is important to have an overview of what data items are present when diagnosing a patient. Therefore, by using the dot display mode, it is possible to improve the listability of a plurality of time-series data, and to grasp many data items at a time within the limited screen size of the display 28A.

In addition, according to the present embodiment, a graph display mode with good visibility, such as a time-dependent change of individual time series data, can be used together, so that both visibility by the graph display mode and listability by the dot display mode are ensured. be able to.

Further, as shown in FIG. 9, only arbitrary data items are displayed in the graph display mode, or as shown in FIG. 10, the width of an arbitrary column is widened to easily confirm detailed data. It is also easy to use.

In FIG. 11, the client terminal 12 repeats the above steps until a display end instruction is given (Y in S1060). For example, when an operation for returning from the dot display mode to the graph display mode or another editing operation such as a request for additional data is performed, the client terminal 12 sends a distribution request or an editing request corresponding thereto to the medical assistance server 11. Send. In the medical assistance server 11, when there is a request for distributing additional data or another editing request from the client terminal 12, the screen editing unit 38 performs editing processing according to the request and distributes the edited screen data. The medical assistance server 11 repeats the editing process until an instruction to end display is given at the client terminal 12 (Y in S1060, Y in S2060).

“Second Embodiment”
As in the second embodiment shown in FIG. 12, a three-dimensional (3D) display mode in which the main display area 41 is displayed in virtual three dimensions may be provided. In the two-dimensional (2D) display mode shown in FIG. 6, the main display area 41 has medical data (time series) on a two-dimensional plane constituted by two axes, a time axis (horizontal axis) and a data array axis (vertical axis). Data). In the three-dimensional display mode shown in FIG. 12, a two-dimensional plane on which medical data (time-series data) is displayed is three-dimensionally displayed using a perspective method. These display modes can be switched by operating the second switching button 61.

As shown in FIG. 12, the three-dimensional display mode uses the perspective method in which a plurality of straight lines parallel to the time axis in the two-dimensional display mode are drawn so as to converge toward the past on the time axis. This is a display mode for three-dimensionally displaying a two-dimensional plane on which data (time-series data) is displayed. In the three-dimensional display mode in this example, the two-dimensional plane in the two-dimensional display mode is virtually set around the rotation axis with the vertical axis (Y axis) orthogonal to the time axis (X axis) as the rotation axis. It is rotating. Such virtual three-dimensional processing is performed using an image processing technique such as setting a virtual three-dimensional space and assigning data on a two-dimensional plane to the set three-dimensional space.

In the 3D display mode, the time scale of the main display area 41 is set so that the time scale is longer than that in the 2D display mode. Thereby, compared with the two-dimensional display mode, the display period of the medical data becomes longer in the three-dimensional display mode. In this example, the display period of the main display area 41 is about one month in August 2014 in the two-dimensional display mode shown in FIG. 6, whereas in the three-dimensional display mode shown in FIG. It is about three months from June to August 2014.

With such 3D display, the display magnification becomes smaller and reduced as it gets past, but at a glance compared to the case where the past and present are switched by screen scrolling operation in 2D display. It is easy to grasp the long-term trend of medical data.

Especially, by combining the perspective method and the lengthening of the time scale, it is possible to grasp the overall trend over a long period of time due to the synergistic effect with the perspective method. By using the 2D display mode for grasping short-term changes and details of time-series data, and using the 3D display mode for grasping overall trends over a long period of time, screen scrolling operations can be performed. It is possible to confirm short-term and long-term time-series data with a simple operation while reducing the amount of time.

The medical data often includes long-term medical care of the patient or intermittent medical care with repeated hospitalization. In such a case, the acquisition period of the medical data is long. Of course, long-term medical data has a long time axis. The medical data is used by a doctor to determine a patient's medical policy. When deciding on a medical treatment policy, it is important to grasp both the presence and details of changes in time series data related to medical treatment in a short period and the overall trend over a long period of time. By using two display modes, the 2D display mode and the 3D display mode, it is possible to easily grasp both the presence and details of changes in the patient's medical data in the short term and the overall trend over the long term. It becomes possible.

Also, as shown in FIG. 12, in the two-dimensional display mode, the horizontal axis of the display screen 15 is set as the time axis, and the vertical axis is set as the data array axis. In the three-dimensional display mode, the data array orthogonal to the time axis is set. The main display area 41 is virtually rotated about the axis as a rotation axis. In the two-dimensional display mode and the three-dimensional display mode, the time axis is the same in the horizontal axis direction, so there is little discomfort even when switching between the two-dimensional display and the three-dimensional display, and it is easy to grasp intuitively.

Also, the time scale of the second time axis 52 in the main display area 41 is naturally switched according to the change of the time scale of the main display area 41. In addition to the second time axis 52, the time scale of the first time axis 51 is also changed in conjunction with the switching of the display mode. In this example, in the three-dimensional display mode, the time scale of the first time axis 51 is changed so that the time scale of the first time axis 51 matches the time scale of the main display area 41. As a result, the same display period as the display period of the main display area 41 for about three months from June 2014 to August 2014 is displayed on the first time axis 51.

Also, the first time axis 51 is two-dimensionally displayed in the three-dimensional display mode similarly to the two-dimensional display mode. On the other hand, the second time axis 52 is three-dimensionally displayed in the same manner as the main display area 41. As described above, the display period of the first time axis 51 is changed in conjunction with the display period of the second time axis 52. Thus, even when the main display area 41 is three-dimensionally displayed, the first time axis 51 is two-dimensionally displayed, so that it is easy to check the display period of the main display area 41 and the timing of medical data.

Also, the item name display area 42 is two-dimensionally displayed in the three-dimensional display mode, unlike the main display area 41. Therefore, it is easy to confirm the item name. Moreover, the item name display area 42 is arranged on the display screen 15 at the right end of the main display area 41, that is, at the end in the current direction on the time axis. In the three-dimensional display mode, the display magnification of the main display area 41 increases toward the current direction. Therefore, by arranging the item name display area 42 at the end in the current direction, the display magnification of the item name display area 42 can be increased, so that the item name can be easily confirmed.

As described above, the client terminal 12 may function as a time-series data display control device. In FIG. 13, portions common to the above embodiment are denoted by common reference numerals and description thereof is omitted.

The difference between the third embodiment and the first embodiment is that the CPU 21A functions as the screen data generation unit 37 and the screen editing unit 38 when the CPU 21A executes the viewer software of the client terminal 12.

In the client terminal 12, the screen data generation unit 37 directly accesses the server group 13, acquires medical data, and generates screen data of the display screen 15. The GUI control unit 33 reproduces the display screen 15 based on the generated screen data and displays it on the display 28A.

For example, one medical support server 11 is installed in an external data center. Thus, an application service such as a data distribution service of the medical assistance server 11 in the data center may be used in the client terminals 12 of a plurality of medical facilities.

In this case, the medical assistance server 11 is communicably connected to client terminals 12 installed in a plurality of medical facilities via, for example, a WAN (Wide Area Network) such as the Internet or a public communication network. The medical assistance server 11 receives requests from the client terminals 12 of a plurality of medical facilities, and provides application services such as distribution of screen data of the display screen 15 to each client terminal.

The installation location and operating entity of the data center and the medical support server 11 may be, for example, one of a plurality of medical facilities or a service company different from the medical facilities. In addition, when using a WAN such as a network, in consideration of information security, construct a VPN (Virtual Private Network) or use a communication protocol with a high security level such as HTTPS (Hypertext Transfer Protocol Secure). Is preferred.

In each of the above embodiments, medical data is described as an example of time series data. However, the present invention can be applied to time series data other than medical data. The present invention is useful when it is necessary to ensure both the visibility of a graph form and the listability of a large number of data items even for time-series data other than medical data. Of course, as described above, regarding the medical data, there are a wide variety of data items that must be referred to during the medical care, and it is highly necessary to ensure both visibility and listability. Therefore, the present invention is particularly useful for medical data.
