GUI Graph Library (gui-graph)

Overview

gui-graph provides graph and chart drawing helpers used by GUI.

All drawing helpers receive an injected drawing context as their first argument:

• ctx.drawLine
• ctx.fillRect
• ctx.drawText
• ctx.rgb

Import

graphs := import('gui-graph')

Exports

• graphRange(values, options?)
• graphMapX(index, count, x, width)
• graphMapY(value, y, height, range)
• drawGraphAxes(ctx, window, x, y, width, height, options?)
• drawLineGraph(ctx, window, x, y, width, height, values, options?)
• drawBarGraph(ctx, window, x, y, width, height, values, options?)
• drawSparkline(ctx, window, x, y, width, height, values, options?)

Notes

• GUI re-exports window-first wrappers (drawLineGraph(...), etc.).
• Option objects support min/max overrides, colors, grid visibility, and labels.
