Research direction

Start at the Trade-off 2D and 3D chart views and the chart key window layout. Reproduce the issue at 1280 × 720, 1440 × 900, and 1920 × 1080 with the key closed, open, and grouped into 8 or more groups. Done when both charts fill the screen and opening, closing, resizing, or grouping the key does not move the plot.

Description

bug P2 role: dev-lead status: ready ui
Details

Bug, balsaPixel preview: the chart key (legend) window pushes the 2D and 3D trade-off charts off the full-screen display. The chart should fill the screen with the key floating over it, like every other window.

Reported by Brian, 2026-10-28. UI didn't reproduce it at 1440 × 900 in headless Chromium: the chart filled the screen under the key. It probably depends on window size or on the key's state (open, wide, after a "Group by").

Steps (Brian): open the balsaPixel preview → Analysis → Trade-off 2D (then 3D) with the Chart key open. The chart is pushed and partly off screen.

Expected:

  • The chart canvas always fills the stage.
  • Windows float over it and never change its size.
  • Opening, closing or resizing the key doesn't move the plot.
Acceptance check

At 1280 × 720, 1440 × 900 and 1920 × 1080, with the key closed, open, and grouped into 8 or more groups, the 2D and 3D chart fill the screen and the plot doesn't move when the key changes.

Notes

Brian, please add the window size and a screenshot if you can (Drive [89] Bug Documentation).
