Charts and graphs

Charts are drawn by Framulus rather than by a charting library, so they inherit the document's colours and fonts and survive rasterisation at any export scale.

Chart

Bar, horizontal bar, line, area, scatter, pie and donut. A chart takes a series of numbers, optional extra series for grouped and multi-line comparisons, labels, and a switch each for value labels and the axis.

Two colours, not one

A chart has the colour it is drawn in and a separate accent for the one figure being pointed at. They are separate fields because collapsing them loses the pointing.

Graph

A Graph plots one or more expressions in x over a domain: sin(x) * 2, x^2 - 3. The expression is held as text and evaluated by a total arithmetic reader. Nothing in a document is ever executed as code.
