Formatting Pie Charts
Contents
Pie Charts in FCS Express are fully formattable. In addition to many of the formatting options shared by all plots (border, size, background, titles, and legend), special formatting options are accessible from the Overlays category. To access these special options:
•Select the Pie Chart and use the Format tab→Plot Options→Overlays command (Figure 5.230), or
•Right-click on the Pie Chart, select Format from the pop-up menu, and choose Overlays from the dropdown.
Special formatting options for Pie Charts are pictured below and include:
•Plotting additional data as a Ring Parameter.
•Explode Parameter for exploding individual sectors (slices) for emphasis.
•Color Parameter for sector (slice) colors.
•Shadow.
•Displaying of Pie Chart as filled pie (default) or "donut".
•Caption Style.
Figure 5.228 Special formatting options for Pie Charts
The formatting options are described in the table below.
Option |
Explanation |
|---|---|
Value Parameter |
The parameter (column) from the Spreadsheet displayed as value of the sector (slice). |
Name Parameter |
The parameter (column) from the Spreadsheet displayed as name of the sector (slice). |
Ring Parameter |
The parameter (column) from the Spreadsheet displayed as sector values of the Ring. See below for more information on displaying additional data as a Ring on Pie Charts. |
Explode Parameter |
The parameter (column) from the Spreadsheet from which the Explode rule derives. A sector (slice) will explode away from the pie for emphasis (e.g., the yellow sector shown below) if its value meets the criterion defined by the Explode rule. See below for more information on how to define am Explode rule. |
Color Parameter |
The parameter (column) from the Spreadsheet defining the display color the sector (slice). See the Pie Charts tutorial for details. |
Show Shadow |
Whether a shadow behind the Pie Chart is shown. |
Color Scheme |
Any of twenty preset coloring schemes which can be applied to the Pie Chart. |
Show as "donut" chart |
Whether the Pie Chart is shown with a hole in the center. |
Hole size |
If the Pie Chart is shown as "donut", the size of the donut hole. |
Caption Style |
The Name, Value, Percentage of the pie (note: "percentage of the pie" differs from "percent gated") or any combination thereof can be shown as text directly beside each sector of the pie or ring. The font of that text can be customized by using the Font button. |
Legend Title |
Text title for the Name parameters listed in the Legend. |
Change data file during Next/Prev/Batch |
Whether the Pie Chart changes during batch processing or in response to a Next/Previous command. It is generally recommended to leave this unchecked (default), as the Pie Chart will update automatically as the data to which it refers is changed. |
Visible |
Whether the Pie Chart is visible within the object. |
To add Ring values as additional data at the periphery of the pie or Exploding for emphasis to a Pie Chart, these values must be entered into designated columns in the Spreadsheet.
To define values for the Ring:
1. Go to an empty column of the Spreadsheet.
2. Enter the value of the Ring for each row (each row corresponds to an individual slice, or sector, of the pie). This value may be freetext or a custom token.
3. Choose the appropriate Spreadsheet column for the Ring Parameter (Figure above)
An example of a Pie Chart with additional Ring values (plotted at the periphery of the Pie) and its associated Spreadsheet is shown in Figure 5.231 below.
1. Go to an empty column of the Spreadsheet
2.Enter the value of the rule for each row (each row corresponds to an individual slice, or sector, of the pie). The rule must be a formula evaluating to "TRUE" or "FALSE"; if "TRUE," the sector (slice) will explode away from the pie. An example of an Explode rule referring to a cell within the Spreadsheet is shown in the Figure below.
3. Choose the appropriate Spreadsheet column for the Explode Parameter (Figure above)
An example of a Pie Chart with the Explode option and its associated Spreadsheet is shown in the Figure below.
