CDP Data Visualization enables you to create Pie charts.

Pie charts are circular statistical graphics that show numerical proportion through relative size of slices; the arc length of each slice is proportional to the quantity it represents. In CDP Data Visualization, pie charts use a default 'doughnut' representation. However, you can change them to the more traditional closed pie configuration by controlling the arc width of the circle, as described in Changing arc width.

The following steps demonstrate how to create a new Pie visual on the Capital Expenditure by Industry dataset. You must first create this dataset, following the steps described in Creating datasets.

For an overview of shelves that specify this visual, see Shelves for pie visuals.

  1. Start a new visual based on the Capital Expenditure by Industry dataset.
    For instructions, see Creating a visual.
  2. In the VISUALS menu, find and click Pie.
    The shelves of the visual changed. They are now Dimensions, Measures, Tooltips, X Trellis, Y Trellis, and Filters. Both Dimensions and Measures are mandatory.
  3. Populate the shelves from the available fields (Dimensions and Measures) in the DATA menu.
    1. Under Dimensions, select industry and drag it to the Dimensions shelf.
    2. Under Measures, select expenditure and drag it to the Measures shelf.

    The Pie visual appears.

  5. Click the pencil/edit icon next to the title of the visualization to enter a name for the visual.

    In this example, the title is changed to 'Capital Expenditures - Pie'. You can also add a brief description of the visual as a subtitle below the title of the visualization.

  6. At the top left corner of the Dashboard Designer, click SAVE.
  7. Optional: Adjust the arc width to close the hole in the middle of the 'doughnut'.
    1. From the visual Settings menu, select the Marks tab, and set Arc Width to 0.
    The default arc width is 80.

    You can also experiment with changing the thickness of the 'doughnut'. See Changing arc width for details on how to adjust the thickness of the 'doughnut'.

  8. Optional: You can adjust the default percentage reporting inside the Tooltip.
    1. From the visual Settings menu, select the Tooltip.
    2. Change the Label for Percentage to 'Percent of Total' and the Decimals included in percentage to '3'.

    To remove the default percentage reporting, unselect the default Include percentage of total in tooltip.
