[BUG] canvas backend stroke width #235

Open ensonmj opened 3 years ago

ensonmj commented 3 years ago

Describe the bug does anyone make stoke width work？

To Reproduce I clone this repo，and try to change style from &RED to let style = Into::<ShapeStyle>::into(&BLUE).stroke_width(100).filled(); in example wasm-demo but nothing changed. (color changed)

Version Information plotters 0.3

Issue persists on Canvas backends with custom WASM project, might be related to the getter/setter of bindgen implementation?

Adding support to the above comment, directly acting on the attributes seemed to work for me:

    let mut style = ShapeStyle::from(RED);
    style.stroke_width=4_u32;

I can confirm that the stroke_width on CanvasBackend isn't working on the latest main. I build the Struct from its field directly:

ShapeStyle{
  color: BLACK.into(),
  filled: true,
  stroke_width: 4
}

The value of the stroke_width doesn't have any effect when using with draw_series.

Value of 10: image

Value of 5: image

Value of 1: image

(The colors are different because i generate a different palette at each run)

Actually it comes from the Backend code that didn't get released since the fix:
