Follow the instructions above to create the basic "Area Chart" Widget, and then perform the following steps to configure a Pie Chart Widget:

2.1. Select a Data Collection

Select a Data Collection that contains the information you would like to use for this Widget.

  • Click the "Data Collection" pulldown, then select from the list of available Data Collections.
  • If you're using the sample CSV data, select "Sample.Data.ChartData2".
  • If there are no Data Collections available in the pulldown, then click here for instructions on how to bring in some Sample Chart Data, or refer to Add/Edit/Remove a Data Collection.

2.2. Name Field

Specifies the field of the Data Collection to use as the name for the wedge. This is the value that will be used for the Legend and DataTips.

  • Click "Name Field" pulldown, and then select an item from the list.
If you are using Sample.Data.ChartData2, then select "Task" for the Name Field.

2.3. Value Field

Specifies the field of the Data Collection that determines the data for each wedge of the pie chart.

  • Click the "Value Field" pulldown, and then select an item from the list.
If you are using Sample.Data.ChartData2, then Select "Feb", as the Value Field.

2.4. Color Selection

Use the color chooser to set the Color and Pattern of each pie slice. The Alpha of each option determines the opacity of the options for the field.

2.5. Labels

Click the "Label" pulldown, and then select an item from the list.

  • None: Does not draw labels. This is the default value.
  • Callout: Draws labels in two vertical stacks on either side of the PieChart control. Shrinks the PieChart if necessary to make room for the labels. Draws key lines from each label to the associated wedge. Shrinks labels as necessary to fit the space provided.
  • Inside: Draws labels inside the chart. Shrinks labels to ensure that they do not overlap each other. Any label that must be drawn too small is hidden from view.
  • InsideWithCallout: Draws labels inside the pie, but if labels are shrunk below a legible size, Flex converts them to callout labels.
  • Outside: Draws labels around the boundary of the PieChart control.
