Axis sections
A measure axis gets a section for each side a measure uses. Its title names the side:
Below the measure axes comes the dimension axis — X-Axis on a vertical chart, Y-Axis on a
horizontal one.
Each section holds one row per measure drawn against that axis, then the axis’s own settings.
Measure appearance
A measure’s row inside its axis section is labeled with its mark glyph and name, followed by the controls that apply to that mark:
Line style and point shape both default to Auto. Auto line style assigns styles by list order, so
measures sharing a color scale can still be told apart. Auto point shape draws a marker-free line;
on a scatter mark it assigns shapes by list order.
A Trend line adds a dashed least-squares regression line in the measure’s color — one per series
when the measure is broken down. It needs a time or numeric dimension to regress against, and is
disabled with a reason on an ordinal one.
Axis settings
Every axis section carries the same controls:
A measure axis additionally controls its scale:
Min and Max are not offered on a side stacked to 100%, whose scale is fixed by definition.
The same scale on both sides
When both sides of a chart are in use, the second section’s header carries a Same scale as the left axis toggle — Same scale as the bottom axis on a horizontal chart. Turning it on draws both sides against one shared scale, so the two series are directly comparable rather than each filling the plot height. A period-over-period comparison column of a measure already on the chart takes the shared scale by default: comparing a measure with its own earlier values is only meaningful on one scale.Reference lines
A reference line marks a target, threshold, or benchmark. Add one from the Axis actions menu (⋮) in any axis header: Add reference line. Every axis with a scale can carry them, measure axes and the dimension axis alike, and each axis can carry several, configured independently. A reference line takes:- A Value — where the line sits on that axis.
- An optional Label naming it, for example
Target 18k. - A Color, Line width, and Line style (solid, dashed, or dotted).
Reference line labels
A reference line with no label renders as a bare rule — the reader has to already know what it means. Type text into Label to name it. Once a label is set, two alignment controls appear next to it:
New labels start at End and Above — the right end of the line, clear of the bars. The label
takes the line’s color, so it always reads as part of that line. Clearing the label removes the text
and leaves the line itself untouched.
