In this module you will learn how to use the Aster Plot Power BI Custom Visual. The Aster Plot is a twist on the standard Pie or Donut Chart. What sets the Aster Plot apart from these visuals is that it has the ability to use a second measure to drive the sweep angle.

- The Aster Plot allows a category that drives the chart and up to 2 measures.
- The first measure controls the depth of each section
- The second measure controls the width of each section
This shows an Aster Plot with multiple categories and two measures controlling the depth and width of each category.
- Under the Format paintbrush there are several options for customizing the appearance of the Aster Plot.
- Turning on the Legend section adds a legend above the Aster Plot by default
- The legend can be moved by changing the Position property
- The title of the legend can be toggled on/off by changing the Title property
- The name of the legend can be modified by adding text to the Legend Name property
- The legend text size and text color can also be adjusted from this section
- By turning on the Detail Labels property you will see data values appear next to each of the slices of the Aster Plot.
- You can then adjust things like the color, text size and number formatting
- Turning on the Outer line property adds a black border line that extends out to make a full circle around the Aster Plot.
This Aster Plot has the Outer line property turned on with a thickness of 5
- In addition to these properties you have a set of settings that appears on every visual to adjust the background color, add a border around the visual and lock the aspect ratio.
