Recommended marker for sparse plots: ●

[cool-RR]

Hey,

For the last few months I've been toying around for different unicode characters to use for plots when there are too few points for the Braille glpyhs to be easily visible. After a few iterations, this is the one I like most: ●

Below is my script that toggles it. Basically I hit * whenever I'm in a plot that's a bit sparse.

@Canvas.api
def toggle_plot_asterisk(canvas: Canvas) -> None:
    if canvas.options.disp_canvas_charset == ' \u25cf':
        canvas.options.disp_canvas_charset = None
    else:
        canvas.options.disp_canvas_charset = ' \u25cf'
   
Canvas.addCommand('*', 'toggle-plot-asterisk', 'toggle_plot_asterisk()')

Neat, @cool-RR ! Where does DEFAULT_DISP_CANVAS_CHARSET come from? I believe you should be able to use None to unset it to the default value, too.

You're right. I fixed the code above now.
