Pie charts are useful when you want to show how much each category contributes to a total.

A Pie chart can display a maximum of 100 data points (per facet, if Faceted). E.g. 10 Y columns x 10 rows or 1 Y column x 100 rows. You can insert a Filter or Sample transform before the chart if you have too much data.

The pies are drawn with the leftmost Y series as the outer pie. You can change the column order using a Reorder Cols transform before the chart.

The X axis data is interpreted as text/label/category values.

The Y axis data must be numeric. You can change the column order using a Reorder Cols transform before the chart.

When numeric data is expected, any non-numeric data is ignored (including empty values). Numeric data is interpreted according to the selected Locale.

The Chart layout can be Grouped or Faceted if you select multiple columns for Y axis data.

General tab

Set the Theme drop-down to choose a palette of colors.

Set Text to modify the chart title text and visibility. If you set Title to Custom the column variables $(X) and $(Y) will be replaced with the names of the X and Y columns. This is particularly useful if you have multiple facets.

Set Legend to modify the legend position and visibility.
