Groups

Bars can have groups (e.g. countries grouped by continents). Bars in the same group have the same color.

A legend is displayed above the chart that shows the group names with their colors. Single-click on the group legend toggles hiding/showing group bars. Double-click shows only this group. Triple-click shows all groups.

To display groups:

• set the showGroups option to true.
• add the field group, to the data items.
