fastplotlib.Cursor

class Cursor(mode='crosshair', size=1.0, color='w', marker='+', edge_color='k', edge_width=0.5, alpha=0.7, size_space='screen')

A cursor that indicates the same position in world-space across subplots.

Parameters:

• mode ("crosshair" | "marker") – cursor mode

• size (float, default 1.0) –

  • if mode == ‘crosshair’, this is the crosshair line thickness

  • if mode == ‘marker’, it’s the size of the marker

  You probably want to use size > 5 if mode is ‘marker’ and size_space is screen

• color (str | Sequence[float] | pygfx.Color | np.ndarray, default "r") – color of the marker

• marker (str, default "+") – marker shape, used if mode == ‘marker’

• edge_color (str | Sequence[float] | pygfx.Color | np.ndarray, default "k") – marker edge color, used if mode == ‘marker’

• edge_width (float, default 0.5) – marker edge widget, used if mode == ‘marker’

• alpha (float, default 0.7) – alpha (transparency) of the cursor

• size_space ("screen" | "world", default "screen") – size space of the cursor, if “screen” the size is exact screen pixels. if “world” the size is in world-space
