Notes

A doughnut of pie plot is also a variation of 2D pie chart just like the pie of pie chart, which has one pie chart and one doughnut chart connected by two straight lines:

  • The pie chart is the main chart, shows whole component distribution in percentages including the wedge "Other" which is the sum of combined wedges.
  • The doughnut chart is the child chart, shows the detailed information of the combined wedges of the wedge "Other".

If you have a 2D pie chart, want to plot a doughnut of pie chart:

  1. Go to the Wedges tab of Plot Details dialog.
  2. Specify how to combine the wedges as the wedge "Other" by setting the Combine Wedges by drop-down list. If you select Percentage or Value for this list, you need enter a value for the Percent/Value <= box. If you select Custom, you can choose the wedges you desired to combine in the Combine column of the Exploding or Combining Wedges table.
  3. Check Show Combined as check box and then select Doughnut from the next drop-down list.
  4. Do customization such as color of the combined wedge, size of the second plot("wedge thickness") and gap between the plots.
