Description

Visualized data processing method and device

Technical Field

The invention relates to the field of data, in particular to a method and a device for processing visualized data.

Background

With the advent of the big data age, data has become one of the most competitive resources in various industries, and thus data mining, big data analysis and data visualization have gradually developed into key technologies or core technologies of various enterprises. The chart is used as a main display mode of data visualization on a webpage or a terminal, and is widely applied to display of data on the webpage or the terminal, so that a user can visually and accurately know the data condition.

Graphs of data are often used to state magnitude or trend of change of values, for example: a line graph, a bar graph, a scatter graph, etc., however, when describing numerical values, since extreme values, i.e., data deviating from a normal data field, may appear in the numerical values, since the graph in the prior art displays a situation that it is difficult for a user to recognize a part of data due to poor adaptivity, it is easy to cause. For example, there is a data set a ═ 7.0, 6.9, 19.5, 14.5, 18.2, 21.5, 25.2, 26.5, 2300.3, 18.3, 13.9, 9.6, fig. 1 is a broken line diagram of the data set a according to the prior art, and as described in connection with fig. 1, since the extreme value 2300.3 appears in the data set a, and is greatly different from other data, the other data are made to behave almost close to 0 in the broken line diagram, and it is difficult for a user to distinguish other values than 2300.3 when reading the broken line diagram. There are two other data sets B {700.0, 600.9, 900.5, 1400.5, 1800.2, 2100.5, 2500.2, 2600.5, 2300.3, 1800.3, 1300.9,900.6} and data set C { -0.2, 0.8, 5.7, 11.3, 17.0, 22.0, 24.8, 24.1, 12.1, 14.1, 8.6, 2.5}, fig. 2 is a broken line diagram of data set B and data set C according to the prior art, and as shown in fig. 2, when it is necessary to make data set B and data set C appear simultaneously in the same graph, the data in data set C is close to 0 because the values in data set B are greatly different from the values in data set C, so that the user cannot distinguish the data in data set C.

Aiming at the problem that display deviation occurs in the data display process due to extreme values in the visual data set, an effective solution is not provided at present.

Under the operating environment, the application provides a processing method of visualized data as shown in fig. 4. Fig. 4 is a flowchart of a processing method of visualization data according to a first embodiment of the present invention.

Step S41 is to acquire a data set displayed in the graph, wherein a plurality of data values included in the data set are sequentially mapped on the coordinate axes of the graph according to a predetermined display structure.

The graph can be a line graph, a bar graph, a scatter graph and the like which are used for representing the numerical value size or the variation trend of the data in the data set. The current common graph is generally two dimensions: x-axis, y-axis; when the dimension is increased, the color value or the presentation mode can be used for distinguishing the dimension, such as the color depth, the circular radius and the like, or other charts can be directly combined, such as the combination of a broken line chart and a pie chart and the like.

Step S43, dividing the data set into a plurality of data areas, the types of the data areas including: a boundary value field containing at least one data value and a boundary blank field containing no data value.

In the above step, the data value in An is used as boundary data to divide the data set An, so that at most n-1 data intervals can be obtained, and the n-1 data intervals can cover all the data in the data set An, and it can be considered that a set of data in An as boundary data is a boundary set, a region not including data other than the boundary data among a plurality of regions in the boundary set is a boundary blank region, and a region including data other than the boundary data is a boundary value region.

FIG. 5 is a diagram illustrating an alternative partitioning of a data set into a plurality of data regions according to an embodiment of the present application. In An alternative embodiment, assuming that the data set An is {600,610,780,1000,1002,1010,1160,1180,1500,1600,1800,1850,1810}, the data values 600,780,1000,1180,1500 and 1810 can be selected as boundary data to form a boundary set Bm {600,780,1000,1180,1500, 1810}, where m has a value range of 1 ≦ m ≦ 6, and as shown in fig. 5, the value fields [ B1, B2], [ B3, B4] and [ B5, B6] are boundary value fields with numerical values, and the value fields [ B2, B3] and [ B4, B5] are boundary blank fields with infinite values.

Step S45, obtaining a display pixel corresponding to the boundary value field according to at least one data value included in the boundary value field.

Here, the display pixels corresponding to the boundary value field are pixels of a display device for displaying the graph. Therefore, when the same graph is displayed in different displays, the display pixels corresponding to the obtained boundary value fields are not necessarily the same.

Step S47, when the display pixels corresponding to the boundary value field satisfy the preset condition, triggering to adjust the linear scale of one or more boundary blank fields contained in the graph.

In An alternative embodiment, still taking the data set An as An example, the previous embodiment may know that the value fields [ B1, B2], [ B3, B4] and [ B5, B6] are boundary value fields with numerical values, and the value fields [ B2, B3] and [ B4, B5] are boundary blank fields with five numerical values, that is, the boundary value fields of the data set An are [600,610 ], [780,1000] and [1002,1010], and the boundary blank fields are [610,780] and [1000,1002 ]. Due to the fact that the display area of the graph is limited, when all data of the data set An are displayed on the same graph, the interval between a plurality of numerical values in the boundary data field may be smaller than the preset pixels of the display device, when the interval between the numerical values is smaller than the preset pixels of the display device, the display result is poor, or the numerical trend is not obvious, and due to the fact that no data value exists in the boundary blank field, the linear proportion of the boundary blank field is adjusted.

In another optional embodiment, a preset pixel is taken as two pixels as An example, where the pixel is a basic unit of a display device, a difference between any two values of display pixels in a boundary value domain on the current display device is obtained, and if there is a difference between any two values of display pixels and/or a display pixel of any one data in a data set on the current display device is smaller than two pixels, a display result of the graph on the current display device cannot clearly show each data value of the data set An and a variation trend of the values, and a linear scale of the boundary margin domain should be adjusted.

The method comprises the steps of acquiring a data set displayed in a chart, wherein a plurality of data values contained in the data set are sequentially mapped on a coordinate axis of the chart according to a preset display structure; dividing the data set into a plurality of data areas, wherein the types of the data areas comprise: a boundary value field containing at least one data value and a boundary blank field without data values; acquiring a display pixel corresponding to the boundary numerical value field according to at least one data value contained in the boundary numerical value field; when the display pixels corresponding to the boundary value field meet the preset condition, a mode of adjusting the linear proportion of one or more boundary blank fields contained in the graph is triggered, the data set is divided into the boundary value field and the boundary blank fields, and the linear proportion of the blank fields contained in the graph is adjusted when the display pixels corresponding to the boundary value field meet the preset condition, so that the purpose of adjusting the linear proportion of the blank fields and improving the visualization effect of the graph is achieved, the technical effect that the display effect of other values is not influenced when extreme values appear in the data set is achieved, and the technical problem that display deviation appears in the data display process due to the fact that the extreme values appear in the visualization data set is solved.

It is easy to note that, in the above-mentioned scheme of the present application, no change is made to data in a data set for display, but only one or more dimensions for displaying the above-mentioned data set are optimized correspondingly, and the above-mentioned optimization process only optimizes dimensions for a boundary blank domain that does not contain a data value, so that the technical purpose of improving the display effect of a chart without changing data in the data set is achieved by the scheme provided by the present application, thereby achieving the technical effect of making the display effect of visualized data better.

Therefore, the technical problem that display deviation occurs in the data display process due to extreme values occurring in the visual data set is solved by the first embodiment provided by the application.

According to the above embodiment of the present application, in step S47, when the display pixels corresponding to the boundary value field satisfy the preset condition, the step of triggering the adjustment of the linear scale of one or more boundary blank fields included in the graph includes:

step S471, determining whether the display pixel corresponding to the boundary value field is smaller than the preset pixel.

It should be noted that, if the display pixel in the boundary value field is greater than or equal to the preset pixel, it may be considered that the value in the boundary value field can be clearly displayed on the graph, and if the display pixel in the boundary value field is smaller than the preset pixel, it may be considered that when the data set is displayed on the graph, the data in the boundary data field may be unrecognizable or the trend of change between the values may be unobvious.

Fig. 6 is a schematic diagram of a pixel display situation according to an embodiment of the present application, as an alternative embodiment, when the preset pixel is 2px, and as shown in fig. 6, the height of the rectangle No. 2 in the figure is 2px, the rectangle No. 1 is smaller than the preset pixel 2px, and the pixels No. 3 to 7 are all larger than the preset pixel 2 px.

In step S473, if the display pixel corresponding to the boundary value field is smaller than the preset pixel, an adjustment instruction is generated.

In an alternative embodiment, referring to fig. 6, if the display pixels corresponding to the boundary value field are shown by the rectangle No. 1 in fig. 6, it is considered that the display pixels corresponding to the boundary value field are smaller than the preset pixels, and the boundary blank field needs to be adjusted.

In step S475, based on the adjustment instruction, the scaling process is triggered to be performed on one or more boundary blank fields in the plurality of data areas, so as to adjust the linear scale of the one or more boundary blank fields in the graph.

In an optional embodiment, an adaptive function of the graph may be set, and a user triggers a boundary and blank field adjustment instruction by selecting a control, scales the boundary and blank field of the graph, and stops scaling when a pixel corresponding to a boundary value field is greater than or equal to a preset pixel.

In another alternative embodiment, adjustment lines may be provided at both ends of the boundary blank field, and the user may adjust the position of the adjustment point through a drag action in the case where it is difficult to recognize a specific value or a variation trend of the value in the boundary value field.

According to the above embodiments of the present application, if the display pixel corresponding to the boundary value field is greater than or equal to the preset pixel, the linear scale of the one or more boundary blank fields in the graph is maintained.

It should be noted that, if the display pixel corresponding to the boundary value field is greater than or equal to the preset pixel, the data in the boundary value field can still be recognized by the user, and the change trend between the data can be more clearly reflected, so that the linear scale of the boundary blank field is maintained.

According to the above embodiment of the present application, step S47, adjusting the linear scale of one or more boundary blank fields contained in the chart includes:

in step S477, the size of the area for displaying the chart is acquired.

Step S479, a preset adjusting proportion value is called according to the size of the area displaying the chart.

Step S4711, scaling the interval width of the one or more boundary blank regions according to the adjustment ratio.

Fig. 7 is a schematic diagram of an alternative processed visualized data according to an embodiment of the present application, and in an alternative embodiment, still taking the data set a in fig. 1 as an example, it can be obtained from fig. 1 that, due to what occurrence of 2300.3 in the data set is extreme, it is difficult to display a trend of changes of other values besides 2300.3 extreme and a specific value, and therefore, it is necessary to adjust the proportion of the boundary blank field in the data set a. First, the area size of the chart is obtained, a preset adjustment proportion is adjusted according to the size of the displayed chart, in this example, the chart is adjusted by using the boundary blank field [26.5, 2300.3] in the data set a as the boundary blank field to be adjusted, and the adjusted result is shown in fig. 7.

It should be noted that the size of the graph display area and the adjustment ratio have a preset corresponding relationship, and after the size of the graph display area is obtained, the display ratio corresponding to the size of the current display area can be searched from the relationship between the size of the graph display area and the adjustment ratio.

According to the above embodiment of the present application, in step S47, when the divided data set includes a plurality of boundary blank fields, triggering the adjustment of the linear scale of one or more boundary blank fields included in the graph includes:

step S4713, acquiring a boundary blank domain meeting the adjustment condition, and adjusting the linear proportion of the boundary blank domain meeting the adjustment condition in the graph; wherein,

acquiring a boundary blank domain meeting an adjusting condition, comprising:

step S47131, using the boundary blank area with the interval value exceeding the preset interval range as the boundary blank area meeting the adjustment condition; or

Step S47133, sorting the plurality of boundary blank domains according to the interval value of each boundary blank domain, and taking one or more boundary blank domains with the highest interval value in the sorting result as the boundary blank domains meeting the adjustment condition; or

Step S47135, comparing the difference between the interval values of any two boundary blank areas with a preset value, and when the difference is greater than or equal to the preset value, taking the boundary blank area with the larger interval value of the two boundary blank areas as the boundary blank area meeting the adjustment condition.

In an alternative embodiment, an interval value for adjusting the boundary blank field is preset, when the interval value of the boundary blank field of the data set is greater than the preset boundary blank field interval value, the boundary blank field is adjusted, and when the interval value of the boundary blank field of the data set is less than or equal to the preset boundary blank field interval value, the boundary blank field is kept not to be adjusted.

In another alternative embodiment, still taking the data set An as An example, sorting the interval sizes of the boundary blank fields [ B2, B3] and [ B4, B5] to obtain [ B4, B5], [ B2, B3], and then selecting [ B4, B5] with a larger region of the boundary blank fields as the boundary blank fields meeting the adjustment condition.

In yet another alternative embodiment, the difference between the interval sizes of [ B2, B3] and [ B4, B5] is calculated and compared with a preset difference, and when the difference between the interval sizes of [ B2, B3] and [ B4, B5] is greater than the preset difference, the [ B4, B5] with a larger margin is determined as the boundary margin satisfying the adjustment condition.

According to the above embodiment of the present application, the display pixel k corresponding to the boundary value field is obtained by calculating according to the following calculation formula:

wherein, B_dSum of regions, A, for characterizing a field of boundary values_MAXFor characterizing the largest value in the data set. A. the_MINFor characterizing the smallest value in the data set, len is used to characterize the size of the region where the chart is displayed.

step S49, identifying the boundary blank region with the adjusted linear proportion, wherein the identification method includes any one of the following methods: color identification, shape identification, brightness identification and chroma identification.

The purpose of the above steps is to mark the adjusted boundary blank region to avoid confusing the relationship between the extreme value and other values.

In an alternative embodiment, the boundary blank region with the adjusted linear scale may be color-identified, that is, the boundary blank region with the adjusted linear scale is colored, so that the user can recognize the region.

According to the above embodiment of the present application, in step S49, after adjusting the linear scale of the one or more boundary blank fields contained in the chart, the method further includes:

in step S491, the boundary point of the boundary blank region with the linear scale adjusted is determined.

Step S493, drawing a corresponding adjustment line based on the boundary point, wherein the adjustment line is perpendicular to the coordinate axis in the graph.

In an alternative embodiment, shown in connection with fig. 7, the adjustment line is perpendicular to the Y-axis of the coordinate axes.

In step S495, dynamically re-rendering the interval width of the boundary blank domain in the diagram when it is monitored that the adjustment line has a drag event.

In the above step, when it is monitored that the jumper wire is dragged, it may be considered that the user adjusts the interval width of the boundary blank field in the graph by dragging the jumper wire, and after the adjustment of the interval width of the boundary blank field is completed, dynamic rendering processing is performed on the new removed interval width of the boundary blank field, where the method of the dynamic rendering processing may be any one of the methods in step S49, but is not limited to this.
