Multi-measurement Single Pie Chart¶

When you have data with only multiple measurements and there is no one dimension to aggregate the data, a multi-dimensional single pie chart can help you generate a pie chart showing the distribution of multiple measurements as a percentage.

DTV has provided a pie chart widget that supports the following data scenarios when your data has both dimensions and measurements.

In this data, the city is the dimension and the data is the measurement. The pie chart will automatically form a diagram by city dimension. For more information about the configuration of the pie chart, see Pie Chart.

In some cases, your data does not have dimensions to aggregate the data, such as the data in the following table.

There are only multiple metrics in this data, and the normal pie chart widget does not support this type of data. In this case, you can use a multi-dimensional single pie chart to generate the chart.
