Module plot 

The charts of a dashboard: the same numbers as crate::chart, laid out for a screen. Besides what to draw, it says where each thing landed, so that whoever shows it can tell what is under the pointer without asking for another picture.

crate::chart stays as it is, so documents already printed keep their looks.

Structs

Bar

A bar as it landed, for drawing it again over the picture.

Candle

What a price did in a category of a ChartKind::Candlestick.

Hit

What is under a point of the chart.

Mark

A value’s place on the chart: where a dot goes, or an active marker.

Plot

A chart laid out.

PlotStyle

The look of a chart. Start from PlotStyle::new and change what differs.

Reference

A dashed line across a chart at a value that matters.

Rule

A thin straight line left out of the picture.

Sector

A slice of a circle or of a ring, for telling what is under the pointer.

Spot

A category of a chart with axes, and the strip of the chart that belongs to it.

Enums

Curve

How a line goes from one point to the next.

Grid

Which gridlines a chart has, as they look on the screen.

LabelAt

Where a label sits relative to what it names.

PolarGrid

The shape of the grid of a radar or radial chart.

Stack

How series share the same category.

Functions

curve_through

The path through points, without its starting move.

draw

Lays a chart out inside rect.

draw_measured

Lays a chart out inside rect, knowing how wide its labels really are.

draw_small

Lays out a scatter chart or a sparkline just as crate::chart does, and says where each value landed: each one owns the strip from halfway to its neighbors.

gapped_slice

A slice as slice_path draws it, with gap left clear all around it: half on each of its sides, of the same width all the way, and half at its ends. What is behind the chart shows through.

rules_around_bars

Gridlines stop where a bar starts and go on where it ends.

slice_path

A slice of a ring around center; a slice of a circle when inner is zero.

value_range

Where a cartesian chart’s value axis starts and ends for this data, as drawing it picks: to ease from one set of data to another along a scale that moves with them, give the frames in between a PlotStyle::domain between the two.

Type Aliases

Measure

How wide text is at a font size, for whoever knows its font.
