Per-Series Colours

Pick a distinct colour for each line using a colour picker, or apply one colour to all series at once.

Line Thickness

Adjust from 0.5 px to 8 px. Thin for dense data, bold for presentation slides.

Font Size

Scale all chart text from 6 pt to 20 pt to suit dashboards or large-format prints.

Axis Range Limits

Set manual min and max for both X and Y axes to zoom in on the range that matters.

Legend Position

Place the legend in any of six positions or hide it for a cleaner export.

Saved with Project

All style settings are stored in your .gpplot.json file. Reload and your chart looks identical.
