Donut chart

A donut chart displays a ring divided into sectors to illustrate a proportion of elements with a number in the center.

The size of each segment corresponds to the percentage of a category in the total amount. A number in the center of a ring depends on the selected measure and indicates the overall total.

Donut charts are a good choice if you need to display a small number of segments.

This configuration is a segment in the overall description of Visualization assets in the workbook. For the complete tutorial, see Use Visualization API.

To describe a donut chart, use the DonutChart configuration:

  • name - your chart's name. Must be unique within the workbook.

  • dataset - the ID of the dataset whose data to visualize.

  • ad_hoc_fields - (optional) describe the calculated fields to use in the chart.

  • visualization - describe the configuration of your chart:

    • kind: donut_chart - specify the chart type.

    • measures - configure the data reference for the chart:

      • source - specify the data source:

        • kind: ref - take the data from the reference data source. This is the dataset specified above.

        • id - specify the ID of the data field from the dataset whose data will be visualized.

    • sort - specify the data field to be used as a sorting reference:

      • source - specify the data source:

        • kind: ref - take the data from the reference data source. This is the dataset specified above.

        • id - specify the ID of the data field from the dataset whose data to use as sorting reference.

      • direction - configure the sorting direction to apply to the chart. You can assign ASC for ascending or DESC for descending.

    • coloring (optional)

      • kind - specify which data type field to use as a color filter. You can specify a dimension or measure.

      • source - specify the data source:

        • kind: ref - take the data from the reference data source. This is the dataset specified above.

        • id - specify the ID of the data field from the dataset whose data will be used as a color filter.

      • palette_id - select the palette to apply to the chart. For most cases, use default-palette.

      • mounts - assign colors from the palette to data points from the source:

        • value - specify the exact value from the source.

        • color_idx - match the above value to a color swatch number in the palette.
