The Canvas Controls
The bar along the bottom of the screen is the Canvas Controls. It
changes how the chart is displayed on your screen — it does not
change the layout or what prints.
From here you can:
- Zoom in and out (− / +), or snap to Fit or 1:1.
- Width fits the chart to the window width.
- Colour applies a screen-only tint (by branch, generation, lineage,
warnings …) to help you inspect the design. - The ··· menu holds extra screen aids, including Edit borders
for dragging the page edge.
Think of it as a working overlay: everything here is for looking at the
chart while you work. Turn on Presentation mode (in ···) to preview
exactly what will print.
