# Changelog

## Plotters Development (?)

### Added
- Font is now support rotation transformation. Use `FontDesc::transform` to apply an rotation to transformation. For example, `font.transform(FontTransform::Rotate90)`.
- ChartContext now support drawing axis description. Use `MeshStyle::x_desc` and `MeshStyle::y_desc` to specify the axis description text.
- Add series label support. `ChartContext::draw_series` now returns a struct `SeriesAnno` that collects the additional information for series labeling. `ChartContext::draw_series_labels` are used to actually draw the series label. (See `examples/chart.rs` for detailed examples)
- Mocking drawing backend.

### Improvement
- Unify `OwnedText` and `Text` into `Text`. Previously, `OwnedText` and `Text` are two seperate types, one holds a `String` another holds a `&str`. Now `OwnedText` is removed.
use `Text::new("text".to_string(),...)` for owned text element and `Text::new("text", ...)` for borrowed text.
- More test cases

## Plotters 0.1.13 (2019-05-31)

### Added
- New abstraction of backend style with `BackendStyle` trait which should be able to extend easier in the future
- Backend support features, now feature options can be used to control which backend should be supported
- Add new trait `IntoDrawingArea`, now we can use `backend.into_drawing_area()` to convert the backend into a raw drawing area
- Now elements support dynamic dispatch, use `element.into_dyn()` to convert the element into a runtime dispatching element

### Improvement
- Improved the overall code quality
- Documentation polish
- Stabilized APIs
- New conversion traits impls
- Now transparent color is ignored by SVG, bitmap and HTML Canvas backend

### Fix
- Changed the oepn-close pattern to a `present` function which indicates the end of drawing one frame
- Fix the but that `ChartBuilder::title` and `ChartBuilder::margin` cannot be called at the same time && `build_ranged` now returning a result.
