A specific description will be given below.

(Various information is displayed in the same time zone)
FIG. 8 is a flow chart showing the basic screen display.
As shown in the flowchart, the following information is displayed on the display 104 of the data analysis PC 100 in FIG.
Specifically, as shown in the flowchart of ST11 in FIG. 8, the "basic screen display processing section (program) 131" in FIG. For example, vital data for 24 hours (24 hours from 8:00 on May 31, 2017 to 8:00 on June 1, 2017), which is the previously set time axis, is displayed.
This 24 hours is an example of the predetermined time range.

At the same time, the event display axis S, which is the time specifying part, is displayed on the screen at an arbitrary time (for example, an intermediate time).
Furthermore, each data of various storage units at the time of the event display axis S is also displayed on the screen.

FIG. 16 is a schematic explanatory diagram showing various information such as vital data displayed on the display 104 of the data analysis PC 100 of FIG.
As shown in FIG. 16, since 24 hours are designated as a time axis at the bottom right of the screen, the information acquired by the data analysis PC 100 follows the flow of time from left to right in the center of the screen, In this case, temperature information (Temp), rotational speed (Arterial) information of the motor 5, pressure (Press) information, and the like are displayed.
A vertical axis-shaped event display axis S is displayed in the center. Information corresponding to the time when the event display axis S is arranged is displayed in the upper frame and the lower frame of the screen. For example, the time in the case of FIG. 16 is "5/31 20:33:04".

For example, the upper left frame of the screen in FIG. 16 is "Flow", and the numerical value at the time "5/31 20:33:04" on the event display axis S is displayed.
Similarly, to the right of "flow rate", the numerical value of "motor rotation speed (Arterial)" is displayed.

In addition, the value of "pH" is displayed in the lower leftmost frame, and this value is the numerical value at the time "5/31 20:33:04" on the event display axis S.

Therefore, by visually recognizing the display 104, a researcher or the like can grasp not only changes in each piece of information, for example, in 24 hours, but also pieces of information at the time indicated by the event display axis S at the same time. is extremely easy to use.

(When changing the time axis (for example, 24 hours))
Here, a case where a researcher or the like changes the time axis (for example, 24 hours) of the screen of FIG. 16 to 12 hours, 1 hour, or 20 minutes because the amount of data is too large will be described below.
FIG. 9 is a schematic flow chart showing the process of changing the time axis (time range to be displayed).

In ST21 of FIG. 9, when the researcher inputs a time axis (time range to be displayed) change signal, in ST22, the "time axis change input processing unit (program) 132" of FIG. Display the change input screen.
Next, in ST23, it is determined whether or not "time axis change information" has been input.
Here, for example, if the researcher inputs "12 hours" from "8:00 to 20:00 on May 31, 2017", the process proceeds to ST24.

In ST24, the same processing unit (program) 132 operates, sets the time axis of the display data to 12 hours from 8:00 to 20:00 on May 31, 2017, and extracts the corresponding data from each storage unit described above. to display.
Note that this time can be freely selected, and can be set to 10 minutes or the like.

(When moving or fixing the event display axis S)
FIG. 10 is a schematic flow chart showing an operation example when the event display axis S of FIG. 16 is moved along the flow of time or fixed.
The operation when the researcher wishes to move the event display axis will be described below with reference to FIG.

First, in ST31 of FIG. 10, the "event display axis operation processing unit (program) 133" of FIG.
Specifically, it is determined whether or not there is an input of "one click" for moving the event display axis S on the screen of FIG.
When "one-click" is performed, the event display axis S is put into a "move mode" state in which the event display axis S can be moved.

Next, when a movement instruction is input in ST32, the process proceeds to ST33. Specifically, in ST33, it is determined whether or not the event display axis S in FIG. 16 has been moved by a pointing operation or the like on the screen.
When it is determined in ST34 that the event display axis S has been moved, the process proceeds to ST35.
In ST35, the value of the information corresponding to the destination time, for example, the numerical value of the flow rate, etc., is displayed.

On the other hand, when it is determined in ST32 that no movement instruction has been input, the process proceeds to ST36.
In ST36, it is determined whether or not there is a fixed input instruction for the event display axis S.
Specifically, it is determined whether or not there is a "one-click" input on the event display axis S.
Next, in ST37, when a fixation instruction is input, movement of the event display axis S is prohibited in ST38.

As described above, in the present embodiment, the researcher inputs a movement instruction or the like to the event display axis S on the screen, thereby moving the event display axis S to an arbitrary position along the time flow on the screen. can be made Then, the values of various information at the destination time can be changed and displayed in the upper and lower frames of FIG. 16 .

Therefore, the researcher can quickly display the values of various information (flow rate, etc.) at the time he/she wants to check on the screen only by operating and moving the event display axis S. FIG.

(When reducing the number of data displayed on the screen, etc.)
FIG. 11 is a schematic flow chart showing an operation example of reducing the number of data such as the flow rate displayed on the screen.
When the researcher wants to reduce the number of data (flow rate, etc.) displayed on the screen, first, as shown in ST41 of FIG. 11, the researcher inputs a signal to the data selection screen , the "display information selection processing unit (program) 134" in FIG. 5 operates to determine whether or not "selection of display data" is completed.

Here, the researcher performs the required data selection.
Next, when it is determined in ST42 that the selection has been completed, the process proceeds to ST43, and only the selected data (flow rate, etc.) can be displayed on the screen.
