Detailed Description
The following detailed description of specific embodiments of the present disclosure is provided in connection with the accompanying drawings. It should be understood that the detailed description and specific examples, while indicating the present disclosure, are given by way of illustration and explanation only, not limitation.
In order to make the technical solutions provided by the embodiments of the present invention easier to understand by those skilled in the art, first, related technologies and application scenarios are briefly described below.
As described in the background, a data table may be displayed in the form of a graph in order to facilitate a user to intuitively analyze data. Each chart has its corresponding chart type indicating the shape of the chart display, e.g., the chart type may be a bar chart, a line chart, a pie chart, etc. A field is displayed in the diagram, and the attribute of the field refers to the value of the field, for example, when the field is "region", the attribute may include "china", "south" and "northeast". In addition, when a field takes a value as a numeric value, the type of the field is a measure, for example, the field takes a value of 1000 or 2000, the type of the field takes a value of 1000 or 2000, and the type of the field takes a value of "sales", that is, a measure, and when a field takes a value other than a numeric value, the type of the field takes a dimension, such as the "region" field described above.
The inventor discovers through analysis of the prior art that in the prior art, when a chart corresponding to the same data table is drawn, the same attribute is displayed in different colors due to the fact that the number or sequence of the field attributes is changed or the data analysis angle is different, and intuitive analysis by a user is not facilitated.
The following description will be given by taking the attribute order change as an example. Illustratively, as shown below, tables 1 and 2 are different presentations for the same data table:
| region of land | |
| Northeast | |
| 5000 | |
| East China | 17000 |
| |
3000 |
| North China | 23000 |
| |
4000 |
| Northwest of China | 3200 |
| Southwest | 6000 |
TABLE 1
TABLE 2
As shown above, the storage order of the attributes "chinese" and "east" in table 1 and table 2 is opposite, where when the pie chart is drawn according to table 1, the drawn chart is shown in fig. 1a, and when the pie chart is drawn according to table 2, the drawn chart is shown in fig. 1b (for comparison, the colors corresponding to "chinese" and "east" are respectively filled by the patterns, and other attributes do not change). Therefore, after the sequence of the fields in the data table is changed, the color display of the same attribute of the drawn chart is inconsistent, as can be clearly seen from fig. 1a and 1b, the colors displayed in "huazhong" in fig. 1a and "huazhong" in fig. 1b are different, in this case, confusion is easily caused to the user, and the user experience is poor.
Based on this, the present disclosure provides a chart color drawing method in view of the above problems found by the inventors. Fig. 2 is a flowchart of a method for drawing a color of a chart according to an embodiment of the present disclosure, and as shown in fig. 2, the method includes:
in S21, a first chart color type of the target chart to be drawn is acquired.
In the present disclosure, an attribute of a chart color type for indicating a color display manner of the chart may be set for the chart, and for example, the chart color type may be a category color, a series color, or a sequence color. The category colors are displayed in the chart according to categories, and each category can display different colors, or a plurality of categories can display the same color, as shown in fig. 3a, wherein "huazhong" and "huabei" are different categories; the series color representation is formed by a plurality of classifications in the chart, and is displayed according to each group of colors, as shown in fig. 3b, wherein a plurality of classifications of books, household kitchenware, furniture and the like are formed into a group and are displayed according to each group of colors, and exemplarily, the corresponding display of "china" is a group of colors; the sequential color indicates that the colors in the chart are displayed as gradation colors.
One chart type may correspond to a plurality of chart color types, as shown in fig. 3a and 3b, the corresponding chart types are bar charts, the chart color model of the chart shown in fig. 3a is a category color, and the chart color type of the chart shown in fig. 3b is a series color. Thus, when setting a chart color type of a chart, a plurality of chart color types supportable by the chart type of the chart may be set first, and then the chart color types may be set for different chart display modes belonging to the same chart type. When the chart color type that can be supported by the chart type is one, the chart color type can be directly set as the chart color type corresponding to the different chart display modes belonging to the chart type. Therefore, when the target chart to be drawn is determined, the chart color type of the target chart can be directly determined.
In S22, it is determined whether a target color model matching a target chart exists in the pre-generated color models according to the first chart color type, the target color model being used to indicate a color of at least one data item corresponding to a valid field in the target chart, the valid field being a field to be color-displayed in the target chart, the data item including an attribute of the at least one valid field.
Wherein the color model may be generated in advance. For a data table, a plurality of fields may be included, and when a chart is drawn, a part of the fields may be selected for drawing the chart, and the selected part of the fields is valid fields. The data item may be an attribute of one valid field, for example, an attribute "huazhong" of the valid field "region" may be one data item, and the data item may also be a combination of attributes of a plurality of valid fields, for example, an attribute "distributor" of the valid field "customer type" and a valid field "sales amount" may be one data item (i.e., a "distributor-sales amount" may be used as a data item). When the valid field is the metric, the valid field can be directly used as the corresponding attribute thereof and combined with other valid fields to be used as the data item.
In S23, if it is determined that the target color model exists, the target chart is drawn based on the target color model.
For example, when the target diagram is drawn according to the target color model, the drawing may be performed according to the color of the data item corresponding to the valid field of the target diagram in the target diagram. Illustratively, the valid field of the target chart is "region", and the color of the attribute corresponding to the valid field is indicated in the target color model. For example, the attribute "huazhong" indicating the valid field "region" in the target color model has a color of a1, the attribute "huadong" has a color of a2, and the attribute "northeast" has a color of A3. When the chart target chart is drawn, if the attributes included in the valid fields are "northeast", "east", "china", "north", "south", "north-west", the attribute "china" drawing color a1, the attribute "east-west" drawing color a2, and the attribute "northeast" drawing color A3 may be displayed.
For another example, when the valid fields of the target chart are "customer type" and "shipping quantity", the color of the data item corresponding to the valid field is indicated in the target color model. For example, the color of the data item "number of distributed customers-shipments" corresponding to the valid field indicated in the target color model is B1, the color of the data item "number of direct marketing customers-shipments" corresponding to the valid field is B2, the color of the data item "number of strategic customers-shipments" corresponding to the valid field is B3, and the color of the data item "number of partner-shipments" corresponding to the valid field is B4. The chart drawn according to the target color model is shown in fig. 3c, in which only the colors corresponding to the Chinese are used for identification.
For the data items of the target color model that do not indicate a color, the data items may be drawn according to a default color, or may be drawn by selecting any other color than the color corresponding to the target color model, which is not limited in this disclosure.
For example, the target graph drawn from table 1 according to the method provided in the present disclosure may be as shown in fig. 1a, and when the table 2 is drawn according to the method provided in the present disclosure, the target graph is as shown in fig. 1c, where in fig. 1c and fig. 1a, the display color corresponding to the attribute "huazhong" is the same, and the display color corresponding to the attribute "huadong" is also the same, so that data can be conveniently and intuitively displayed.
In another embodiment, when the histogram is drawn according to table 1, the matched target color model may be determined according to the valid field and the chart color type thereof, and in this embodiment, the determined target color model corresponding to the histogram is the same as the target color model corresponding to the pie chart, so that the histogram may be drawn according to the target color model, so that the same color is displayed in the same attribute in the histogram and the pie chart. The manner of matching the target color model and drawing the chart according to the target color model is described in detail above, and is not described herein again.
In the above technical solution, by obtaining the chart color type of the target chart and determining whether a target color model matching the target chart exists in the pre-generated color models, if the target color model exists, the target chart can be drawn according to the target color model. Therefore, by the technical scheme, the target graph can be drawn according to the target color model matched with the target graph when the target graph is drawn, on one hand, the change of the number of the attributes and the attribute sequence in the data table cannot cause the change of the effective field, so that the target data model cannot be changed, and the problem of inconsistent attribute color display caused by the change of the number of the attributes and the attribute sequence can be effectively avoided. On the other hand, under the condition that the target color models corresponding to the graphs at different data analysis angles are the same, the colors of the graphs of different graph types can be kept consistent, the phenomenon that the colors of the same attribute are displayed in the graphs of different types in an inconsistent manner due to different data analysis angles is avoided, the consistency of color display of the attribute corresponding to the effective field in the target graph can be effectively guaranteed, uniform and visual graph display is provided, the practicability of data visualization is improved, meanwhile, the use requirements of users are met, and the use experience of the users is improved.
In order to make the technical solutions provided by the embodiments of the present invention easier to understand by those skilled in the art, the following first describes each step in the above-mentioned methods in detail.
Alternatively, the color model may be generated by:
the valid fields of the labeled chart are determined.
The labeled chart may be a frame structure corresponding to the color model, that is, there is no actual data in the labeled chart. During initialization, the valid field of the label chart is empty, and the valid field can be specified by a user. When the valid field is determined according to the operation of the user, the valid field can be written into the label chart, so that the valid field of the label chart is determined.
Determining a color of at least one data item corresponding to a valid field in the label chart. When the valid field in the label chart is determined, the valid field may correspond to a plurality of attributes, each attribute may serve as a data item, and a plurality of valid fields may be combined to serve as a data item. When determining the color corresponding to the data item, the color of the data item corresponding to the valid field may be determined in response to an indication of a user, and the determined color of the data item corresponding to the valid field may be written into the mark chart. Optionally, the valid fields in the color model of category color generally select one or two fields with type as dimension, the valid fields in the color model of series color generally consist of fields with type as dimension or jointly consist of fields with type as dimension and type as measure, and the valid fields in the color model of sequence color generally select one field with type as measure.
The color may be specified for each data item corresponding to the valid field, or may also be specified for a part of data items corresponding to the valid field, which may be set according to an actual usage scenario, and this disclosure does not limit this.
And generating a color model corresponding to the second chart color type according to the corresponding relation among the second chart color type of the labeled chart, the effective field in the labeled chart and the color of at least one data item corresponding to the effective field in the labeled chart.
The chart color type of the label chart can be preset, and the chart color type is described above and is not described herein again. Therefore, the corresponding relation among the effective field written in the mark chart, the color of the data item corresponding to the effective field and the chart color type of the mark chart can be determined. For example, a color model may be generated according to the correspondence relationship, and the label chart may also be used as the color model.
Therefore, by the technical scheme, the color model can be subjected to unified and standardized structure description, so that the application range of the color model is improved, and data support is provided for ensuring the color display consistency of the chart.
Optionally, in S22, according to the first chart color type, an exemplary implementation manner of determining whether there is a target color model matching the target chart in the pre-generated color models is as follows:
and when the first chart color type is a category color or a series color, if a color model with the corresponding effective field consistent with the effective field of the target chart exists in the color models which are generated in advance and correspond to the first chart color type, determining the color model as the target color model.
When the color type of the first chart is a category color or a series color, the displayed color is related to the content corresponding to each valid field, so that whether the valid field of the target chart is consistent with the valid field corresponding to the color model needs to be further determined, and the target chart can be drawn according to the color model when the valid fields of the target chart are consistent.
Illustratively, the valid fields corresponding to the color model are consistent with the valid fields of the target chart, including:
the number of the effective fields of the target chart and the effective fields corresponding to the color model are the same as the field expression.
Wherein, in one embodiment, a field can be uniquely represented by a field expression. For example, the field expression may be a field identifier, and when the names of the valid fields are different, but the field identifiers are the same, and the number of valid fields is the same, it may be determined that the valid fields of the target chart are consistent with the valid fields corresponding to the color model. In another embodiment, the field expression may be represented by a concat () function. Here, the concat () function is an existing algorithm, and is not described herein again. Therefore, when the name of the effective field is changed according to the actual use scene, but the field identifier of the effective field is not changed, the matching accuracy of the target chart and the color model can be effectively ensured, and meanwhile, the requirement of the user for personalized customization can be met.
Optionally, in S22, according to the first chart color type, another exemplary implementation manner of determining whether there is a target color model matching the target chart in the pre-generated color models is as follows, including:
and when the first chart color type is a sequential color, if the type of the effective field of the target chart is measurement, determining one of the color models which are generated in advance and correspond to the first chart color type as the target color model.
And the type of the effective field corresponding to the color model with the chart color type being the sequential color is the measurement. The color model of the chart color type of the sequential color is used for characterizing the magnitude relation between numerical values, so that the valid fields of which the types are measurement can be applied to the color model of the sequential color.
Thus, when the first chart color type is sequential color, the target chart can be drawn based on the color model of the sequential color when the type of the valid field of the target chart is measurement. For example, if there are a plurality of color models of sequential colors, one of the color models may be randomly or by default selected as the target color model, or one of the color models may be designated as the target color model by the user, which is not limited in this disclosure. When the target color model is determined, if the color of the minimum value of the effective field is indicated in the target color model, the color may be gradually deepened or lightened according to the increase of the attribute value of the effective field, so as to achieve the gradual change effect. If the colors of the minimum value and the maximum value of the valid field are indicated in the target color model, the color corresponding to the intermediate value can be uniformly and gradually changed based on the colors of the maximum value and the minimum value. The implementation manner of the color gradient is the prior art, and is not described herein again.
Therefore, according to the technical scheme, when the first chart color type is the sequential color, the target color model matched with the target chart is determined by verifying the type of the effective field of the target chart, so that the application range of the color model can be effectively improved, and the use experience of a user is ensured.
In addition, according to different use scenes, after the target diagram is drawn, the diagram type of the target diagram may need to be changed. However, in the prior art, when the chart type is changed, the color of the chart is readjusted after the pie chart shown in fig. 1a is converted into a bar chart, which is shown in fig. 3a, and the color display of the bar chart is inconsistent with that of fig. 1 a. Moreover, during the switching process between the bar chart and the pie chart, the user may be required to set the line-column conversion to obtain the chart meeting the requirement of the user.
In view of the above problems, the present disclosure also provides the following embodiments. Optionally, after the step 23 of drawing the target chart according to the target color model, the method further comprises:
when the chart type of the target chart is changed, if the third chart color type of the changed target chart is consistent with the first chart color type, drawing the changed target chart according to the target color model.
Illustratively, the chart type of the drawn target chart is a pie chart. When the pie chart is changed into a bar chart for displaying, whether a third chart color type corresponding to the bar chart is consistent with a first chart color type of the pie chart can be determined, and if the first chart color type is a category color and the third chart color type is a category color, the bar chart can be directly drawn according to a target color model. If the first chart color type is a category color and the third chart color type is a series color, the first chart color type and the third chart color type are not consistent, and at this time, whether a target color model matched with the modified target chart exists in the pre-generated color model or not can be determined again, so that the modified target chart is drawn.
