Designing a Custom Donut Chart

A donut chart, similar to a pie chart, allows you to compare between categories and visualize part to whole relationships. A donut chart has the added advantage of having a blank space in the middle where extra information can be supplemented.

To design a custom donut chart:

  1. Build a report.
  2. Under the CHART CONFIGURATION section, select the DONUT chart.
  3. Enter or select the required field information .
    The following table describes the field information in this section:
    Field Description
    *Group by Select a value from the dropdown menu on the basis of which report data will be grouped. For example: Device Name.

    • Average: Calculates the average value of a given set of data.
    • Sum: Calculates the sum of all values in a given set of data.

    1. Click on the coloured value boxes to display the color palette.
    2. Choose the desired color.
    3. Similarly click the coloured boxes and choose different colors from the palette for the different values,
