Bar Chart

Bars over a category axis, horizontal or stacked. The default choice for comparing discrete categories — output per line, downtime by reason, scrap by shift.

Reach for it when you need:

• Downtime reasons this week
• Output per line or per shift

Component name: BarChart · Category: Chart

In the palette: Bars over a category axis — toggle horizontal or stack. Bind data to a named query; click a bar to expose {{point.value}}.

Right-click behaves differently in the Designer

contextmenu fires your configured actions at runtime only — in LiveView and in preview. On the Designer canvas the right-click is captured to open the Event Manager, so testing it there will not run your actions. Test right-click in preview.
