Improved

Fixed

• Fix the plotters crate's edition requirement

Release tag for Plotters 0.3.2 release

Added

• Pie element (by @hhamana)

Improved

• Improved documentation for predefined colors. (Thanks to @siefkenj)
• Introduce the full Material Design 2014 Color Palette. (Thanks to @siefkenj)
• Massive documentation improvements (Thanks to @facorread and many others)

Fixed

• More float point axis key point algorithm fixes (@38)
• Default rasterizer fixes (@shinmili and @38)

Improved

• Surface series now supports more customizations
• Z-orde support for 3D plots
• Allow passing colors by value and reference (thanks to chrisduerr)

Fixed

• Infinite loop / panic when the axis range is zero
• UB in minifb example (thanks to TheEdward162)
• Examples that uses old APIs (thanks to chrisduerr)

This is the next major release of Plotters, see release notes for more details.

Added

• The plotters backend API crate is introduced which allows third-party backend.
• Allow slice used as a coordinate if the item type implements PartialOrd.
• Linspace coordinate type, which allows define a discrete coordinate on continuous value types (such as f32, DateTime, etc) with a step specification
• Nested coordinate type, now we support define pair of category and nested values as nested coordinate.
• Introduce backend crates: plotters-bitmap, plotters-svg, plotters-cairo, plotters-canvas, plotters-console
• 3D Plotting features

Fixed

• Adjust Canvas backend size with DPR (Thanks to Marius-Mueller)

Improvement

• Enhanced key point algorithms: New key point hint trait are used for key point algorithms && many improvement on key point algorithms for different types
• Renamed MeshStyle::line\_style\_1 and MeshStyle::line\_style\_2 to bold\_line\_style and light\_line\_style
• Reorganize the "plotters::coord" namespace
• Improved discrete coordinate trait
• Split backend code into isolated crates and can be maintained indepdendenly
• Category coordinate is now replaced by slice coordinate
• Removing the requirement for Debug trait for chart coordinate, allows ranged coordinate define its own formatting function.

Removed

• The Path name alias for PathElement
• Most code plotters::drawing::backend\_impl::\* (expect MockedBackend for testing purpose) is removed due to crate split.
• Piston backend due to the Piston project seems not actively developing

Improvement

• Move the sample images and other documentation data out of this repository.

Fix

• Make drawing errors shareable across threads. Otherwise, it causes compile error in some cases. (Thanks to @rkarp)

Added

• Add relative sizing by added function DrawingArea::relative_to_height and DrawingArea::relative_to_width.
• Added piston backend, now we can render plot on a window and dynamically render the plot

Improved

• Creating drawing area with &Rc<RefCell<DrawingBackend>>. Previously, the drawing area creation requires take over the drawing backend ownership. But sometimes the drawing backend may have additional options. With new API, this can be done by putting the backend drawing area into smart pointers, thus, the drawing backend is accessible after creates the root drawing area.
