Bar charts compare values across discrete categories. Use them when the magnitude of individual values matters and direct comparison between categories is the goal.

​
Variants

​
Basic

One dimension on the X axis, one measure on the Y axis. Each category gets a single bar.

​
Grouped

Each series renders as a separate cluster of bars side-by-side at every X-axis value. Best for comparing absolute values across multiple series at each category.

​
Stacked

Series are stacked on top of each other at each X-axis value. Use when you want to show both individual contributions and the total at a glance.

​
Percentage stacked (Stack %)

Each stack is normalized to 100%, showing each series as a proportion of the total per X-axis value. Use when relative distribution matters more than absolute values.

​
Horizontal

All three vertical variants are also available horizontally. Horizontal bars work well for long category labels, many categories, or when a left-to-right reading direction feels more natural.

​
Composite (bar + line)

Assign one series to the right Y axis and set its mark type to Line in series configuration. This creates a dual-axis chart — useful for overlaying a rate on top of volume data (e.g. order count as bars, revenue per order as a line).

​
Stacking

Stacking behavior is set in the Color & stacking section of the Style tab:

AutomaticCube picks the best option based on your data
StackSeries at the same X value are stacked
GroupSeries at the same X value are placed side-by-side
OverlaySeries are drawn on top of each other (rarely useful for bars)
Stack %Series are stacked and normalized to 100%
Stacking can also be set independently per Y-axis series — enabling grouped clusters of stacked sub-groups.

​
Data labels

Bar charts support totals labels on stacked charts — showing the aggregate value above each full stack. Enable Data Labels in the Fields tab, then configure:
  • Format — number format applied to the label value
  • Font size — size of the label text
  • Position — Outside end, Inside end, Inside center, or Inside base

​
Axis behavior

Bar charts use an ordinal X axis — each bar is labeled independently, the axis is not time-aware, and categories not present in the result set are not plotted. With time fields, bars are ordered ascending automatically. For other data types, order follows the results table sort. Tooltips on stacked bars are scoped to the segment under the cursor, not the full stack total.
