.PIE SET DATASET

This subroutine associates a dataset with the "current" pie chart.

Usage:

      PASS         <dataset_name>             FIELD            SHARE? N
      GOSUB    0CD .PIE SET DATASET
      *        Check for error
      IF       0CD .PIE SET DATASET           NE

Description:

This associates the named dataset with the "current" pie chart.

When a Pie chart is initialized via .CHART INITIALIZE, a default dataset is initialized for you (unless you have already initialized a dataset separately, see Datasets Overview for more information).

If you are working with multiple datasets, this routine allows you to link a particular dataset to the chart. That is the dataset that will be used when the chart is rendered.

If <dataset_name> is specified, it must refer to a previously initialized dataset or blank to refer to the default dataset for the chart. If you do not pass <dataset_name>, then whatever is the "current" dataset will be associated with the "current" chart.

After associating the dataset with the "current" chart, that dataset becomes the "current" dataset.
