Bar Chart

A bar chart will draw categories and values in a familiar bar-layout. The bar chart will require you to choose the following selections:

  • Category: a text field. These will be the labels on the bars.

  • Value: a numeric field. This will be the height of the bars.

  • Group: Optionally, a second textual field. When ``Grouping'' is enabled in the advanced settings, the group can be used to draw a stacked bar chart, with several groups per category.

Examples

Stacked Bar Chart
