Build a Pie Chart

To build a Pie Chart

1. Connect to the sample data source in Aqua Data Studio.
2. From the Dimensions pane, select OrderDate.
3. From the Measures pane, select Profit.
4. Click the  tab, and then click.Visualization builds a Pie Chart.
   

In the sample data source, we have changed the YEAR(OrderDate) to QUARTER(OrderDate). You will notice that Visualization has moved the QUARTER(OrderDate) Dimension to the Color Deck but retained the SUM(Profit) Measure in the Rows Deck. You will also notice that Size Deck is disabled. You can use this deck when you plot a symbol map via Geo Deck.

Show Data Labels and Percentage

When Visualization builds a Pie chart, the data labels and show percentage values are not displayed by default on the chart slices.

To view data labels and percentage value on the pie slices

1. In the Color Deck, hold down the CTRL key and select QUARTER(OrderDate) and then place it in the Label Deck.
   
2. Click the Label Deck and then select the Show percentage check box.
   

Configure a Center Hole

You can configure a hole in the center of the chart. The hole adds to the visualization experience of the Pie chart. Depending on the need, you can increase or decrease the size of the rings. 

To configure a center hole

1. In the Chart Properties Deck, click the Options Deck.
2. Move the slider to the right, to configure a hole and the desired width of the hole. 
   If you click Reset Center Hole Size, Visual Analytics reverts the chart to its original appearance.
   

Plot a Symbol Map

You can plot a symbol map by placing a geographical dimension in the Geo Deck. When you plot a symbol map, you will notice that Axes and Label Decks are disabled. 

To plot a Symbol Map Chart

• From the Dimensions pane, move the State Dimension and place it in the Geo Deck.
  

Visual Analytics plots pies for each state based on profit. We have filtered records to concentrate only on the US region. For more information on Symbol Map, see How to Make a Symbol Map.
