   Table 1 Pie chart parameters

   Type	Parameter	Description
   Standard	Format	Select K,Mil,Bil, 1,000,000, or Byte,KB,MB from the drop-down list to specify the format of the Y axis.
   	Unit	Customize the unit of the Y axis.
   	Decimal Places	Sets the number of decimal places to be displayed.
   	Title Font Size	Sets the font size of the chart title.
   Pie Chart	Pie Chart Type	Includes pie, cyclic, and Coxcomb charts. Pie A pie chart displays the percentage of each part in the whole. It divides a circle into different sectors. The area (or arc length and center angle) of each sector corresponds to the proportion of the data represented by the sector. In this way, the relationship between each part and the whole is intuitively displayed. ‌ Cyclic Essentially, a cyclic chart hollows out the center of a pie chart. Cyclic charts are better than pie charts in the following aspects: Cyclic charts display more information such as the total number. It is not intuitive to compare two pie charts directly. You can compare two cyclic charts by the cyclic bar length. Coxcomb A Coxcomb chart is not a cyclic chart in essence. Instead, it is a bar chart drawn in the polar coordinate system. Each category is evenly divided by an arc. The radius of the arc indicates the data size. Coxcomb charts are better than pie charts in the following aspects: A pie chart can contain a maximum of 10 categorized data records, while a Coxcomb chart can contain 10 to 30 data records. Because the radius and area are squared, a Coxcomb chart magnifies the difference between the values of each category. It is suitable for comparing the values of similar sizes. Due to the periodicity of a circle, a Coxcomb chart is also suitable for displaying data by time period, such as by week and month.
   	Show Scale	After this function is enabled, text labels are displayed on the pie chart to describe data details, such as the value and name.
   	Scale Text	This parameter can be set to Category, Percent, Category: %, or Category: Value (%).
   	Label Position	After Show Scale is enabled, you can set this parameter to adjust the position of the label in the chart.
   Query/Analysis	Value	Specifies the value corresponding to the categorized data.
   	Layer 1 Data
   	Category	Specifies the categorized data.
   	Display as Sectors	Specifies the number of pie sectors to be displayed.
   	Sort By	Specifies the ascending or descending order.
   	Display Rest as Others	Specifies whether to display the data of other types as Other.
   	Add Layer	Click Add Layer and set the data of the second layer. The data of each layer includes the category, display sectors, sorting mode, and displaying rest sectors as others.
   Legend	Hide Legend	After this function is enabled, you can hide the legend and its content.
   	Legend	Select Value or Percent, or both.
   	Legend Position	Position of the legend in the chart. Select Top or Right.
   Graphics	Outer Radius	Specifies the outer radius of the pie chart. The value ranges from 40 to 100.
   	Inside Radius	Specifies the inside radius of the pie chart. The value ranges from 0 to 100.
   	Top Margin	Specifies the distance between the axis and the upper boundary of the graph.
   	Bottom Margin	Specifies the distance between the axis and the lower boundary of the graph.
   	Left Margin	Specifies the distance between the axis and the left boundary of the graph.
   	Right Margin	Specifies the distance between the axis and the right boundary of the graph.
