Description

Automatic point-distance chart generation method and system
Technical Field
The disclosure belongs to the technical field of data visualization, and particularly relates to a method and a system for automatically generating a point distance chart.
Background
The statements in this section merely provide background information related to the present disclosure and may not necessarily constitute prior art.
The presentation of data contrast is a common application in data visualization. When comparing multiple data values, one typically uses a histogram, pie chart, or other chart. In such a graph, one would also use a position of the use point to express a value of the data size. This type of chart does not have a uniform name and is referred to herein as a dot-space chart. The point distance graph resembles a histogram, i.e., the magnitude of the values is represented using the origin at the endpoints of the histogram rather than using a bar. The graph can better convey numerical information because the point is located from the point used by the graph rather than the length of the column or the angle of the pie chart. The point-to-point diagram has fewer graphic elements, can make the diagram more sparse and concise, and can leave more space compared with the histogram, so that people can read and understand the diagram more easily. And because the space left by the dot-space graph is more, the graph is more suitable for expressing multi-series data. Thus, the dot pitch graph is a more flexible and efficient numerical comparison graph in addition to the histogram.
The inventor finds that, because the diagram is not a basic diagram type, no direct method and corresponding functional module exist for making and generating the diagram, most of the cases can only be made in a manual mode, and the process is complex.

Detailed Description
The present disclosure is further described with reference to the following drawings and examples.
It should be noted that the following detailed description is exemplary and is intended to provide further explanation of the disclosure. Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this disclosure belongs.
It is noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of example embodiments according to the present disclosure. As used herein, the singular forms "a", "an" and "the" are intended to include the plural forms as well, and it should be understood that when the terms "comprises" and/or "comprising" are used in this specification, they specify the presence of stated features, steps, operations, devices, components, and/or combinations thereof, unless the context clearly indicates otherwise.
The embodiments and features of the embodiments in the present disclosure may be combined with each other without conflict.
The first embodiment is as follows:
the embodiment aims to provide an automatic point distance chart generation method.
A method for automatically generating a point distance chart comprises the following steps:
setting a data storage area, a temporary area and a dot pitch chart area in an Excel page in advance;
inputting the acquired data into a table based on the row and column names of the data storage area;
reading data in a data storage area by using a VBA code, copying a column where a name is located in the data storage area and a column where the data is located to a temporary area, calculating an equal score value based on the data, and determining the size of the equal score value in the temporary area;
and generating a dot pitch chart by using VBA codes based on the temporary region data in a mode of combining a histogram and a scatter chart.
Specifically, for ease of understanding, the embodiments of the present disclosure are described in detail below with reference to the accompanying drawings:
in order to better illustrate the generation idea of the invention, a description of the diagram and the implementation principle of the key steps are given first:
as shown in fig. 1, is raw data; fig. 2 is a graph of dot pitch finally generated by the scheme of the present disclosure, and fig. 3 is temporary data in the generation process of the method of the present disclosure. The temporary data can be deleted or saved in other pages by using a program after the chart generation is completed. For ease of description, the temporary data in FIG. 3 uses X, Y, and Z to identify three columns, respectively. Where X and Y are listed in the original data (i.e., FIG. 1) in the "name" column and the "value" column, which are identical. The data of Z is the position value obtained by dividing the value 1 by n. For example, if the original data is 10 lines of data in total, 1 needs to be divided into 11 equal parts, so that the value of each small segment is 1/11-0.090909. Thus, the Z columns are 0.090909 larger for the first row than 0 and 0.090909 larger for the second row than the first row. By analogy, the difference between the last row and 1 is also 0.090909. The function of Z will be described with reference to fig. 2.
The main idea of the solution described in the present disclosure is a method of using two charts to be presented in the same area. The first graph is a lateral histogram based on X and Y columns. It can be seen from fig. 2 that the size of each datum corresponds to the distance from the right black dot to the left graph boundary. And the columnar elements in the histogram are hidden here. The purpose of the chart is to concatenate the data names into values, i.e., if the original data appears to be out of order, the end result will be adjusted in real time. The second graph is a scatter diagram, and the data on the horizontal axis of the scatter diagram is the Y column, i.e. the raw data. The vertical axis of the scatter plot is Z column data. Since the values of the Z column data simulate the highly averaged distribution of the graph, the distribution is averaged along the vertical axis of the graph. For example, if only the data in the Y and Z columns of FIG. 3 are viewed, the data corresponds to the position of the scatter plot in FIG. 2. That is, X columns are horizontal axis positions of the black dots, and Y columns are vertical axis positions of the black dots.
Based on the above description, the scheme disclosed by the present disclosure includes the following specific steps:
step 1: enabling generation of auxiliary data in VBA according to data area
Assume that the area name of the column in fig. 1 where the name of the original data is located is DataName, and the area where the data is located is DataValue. To generate the temporary data in fig. 3. Firstly, a temporary area is created and named according to the size of an original data area, and the VBA code of the temporary area is as follows: in the code, nameRng is used to represent the X column area, dataRng is used to represent the Y column, and dotDataRng is used to represent the Z column in FIG. 3. And copied using a copy function. The new area is 3 units to the right of the original area. The number of area lines is enlarged for convenience of the later n division for calculating 1.
---------------------------
Set nameRng=Range("DataName").Resize(Range("DataName")._
Rows.Count+2).Offset(-1,4)
Set dataRng=Range("DataValue").Resize(Range("DataValue")._
Rows.Count+2).Offset(-1,3)
Set dotDataRng=dataRng.Offset(0,1)
Range("DataName").Copy nameRng.Offset(1,0)
Range("DataValue").Copy dataRng.Offset(1,0)
---------------------------
Next, continuing to calculate the equal score value and fill the Z column, specifically using the following codes: the number of aliquots is first calculated, the variable tNum. The size of each segment, i.e. the value of the variable u, is then calculated. The Z column is then filled in using a loop.
---------------------------
tNum=dotDataRng.Rows.Count-1
u=(1/tNum)
For i=0To dotDataRng.Rows.Count-1
dotDataRng.Cells(i+1,1)=i*u
Next i
---------------------------
Step 2: generating a histogram and a scatter plot in the VBA;
the first chart, the histogram, is generated using the code, and the vertical grid lines are deleted and the horizontal grid lines are displayed. The following codes are mainly adopted, specifically, Union (nameRng, dataRng) combines X and Y columns. The first two sentences of the code are used for generating charts, and the last two sentences are used for setting grid lines. After the setting is performed, a boundary may be added to the drawing area in the diagram and a grid line format may be set. For example, the horizontal grid lines in fig. 2 are dashed lines. Such steps may be performed during the final adjustment and are therefore not described in further detail.
---------------------------
ActiveSheet.Shapes.AddChart2(216,xlBarClustered).Select
ActiveChart.SetSourceData Source:=Union(nameRng,dataRng)
ActiveChart.SetElement(msoElementPrimaryValueGridLinesNone)
ActiveChart.Axes(xlCategory).HasMajorGridlines=True
---------------------------
Generating the scatter plot specifically employs code that specifically steps adding a new series and setting the series as the scatter plot.
---------------------------
ActiveChart.PlotArea.Select
ActiveChart.SeriesCollection.NewSeries
ActiveChart.FullSeriesCollection(2).Select
ActiveChart.FullSeriesCollection(2).ChartType=xlXYScatter
---------------------------
And step 3: adjusting the data source and the setting of the table number axis in the table in the VBA;
the code for setting the horizontal axis of the scatter plot as a Y column and the vertical axis as Z, and placing the chart elements on the axes instead of in the axes is as follows. The first two rows of the code are to set the horizontal axis data as Y columns. The next two rows are with the vertical axis set to Z columns. The latter two rows are for placing the chart elements on the axes.
---------------------------
ActiveChart.FullSeriesCollection(2).XValues=_
dataRng.Resize(dataRng.Rows.Count-2).Offset(1,0)
ActiveChart.FullSeriesCollection(2).Values=_
dotDataRng.Resize(dotDataRng.Rows.Count-2).Offset(1,0)
ActiveChart.Axes(xlCategory).Select
ActiveChart.Axes(xlCategory).AxisBetweenCategories=False
---------------------------
And 4, step 4: and further adjusting and setting the generated graph.
In this step, other elements of the diagram may be added and deleted or existing elements may be set, for example, using the following statements:
ActiveChart.SetElement(msoElementSecondaryCategoryAxisShow)
the values on the horizontal axis of the graph may be displayed, i.e., the lowest value label in fig. 2.
Further, in order to prove the effectiveness of the method of the present disclosure, in this embodiment, an example of generating a point distance chart is given:
FIG. 4 is a diagram illustrating the original data in the case of a large amount of data; FIG. 5 is a graph of dot pitch generated based on the data shown in FIG. 4 using the solution of the present disclosure; FIG. 6 is a graph illustrating the results sorted based on the dot spacing chart of FIG. 5; in connection with the graph it can be found that the point distance graph resembles a histogram, i.e. the value size is represented using the origin at the end points of the histogram instead of using a bar. The graph can better convey numerical information because the point is located from the point used by the graph rather than the length of the column or the angle of the pie chart. The point-to-point diagram has fewer graphic elements, can make the diagram more sparse and concise, and can leave more space compared with the histogram, so that people can read and understand the diagram more easily. And because the space left by the dot-space graph is more, the graph is more suitable for expressing multi-series data. Thus, the dot pitch graph is a more flexible and efficient numerical comparison graph in addition to the histogram.

and the dot pitch chart generating unit is used for generating a dot pitch chart by using VBA codes in a mode of combining a histogram and a scatter chart based on the temporary area data.
