Method set_dashes

lib/matplotlib/lines.py:1339–1361

Set the dash sequence. The dash sequence is a sequence of floats of even length describing the length of dashes and spaces in points. For example, (5, 2, 1, 2) describes a sequence of 5 point and 1 point dashes separated by 2 point spaces. See also

        Set the dash sequence.

        The dash sequence is a sequence of floats of even length describing
        the length of dashes and spaces in points.

        For example, (5, 2, 1, 2) describes a sequence of 5 point and 1 point
        dashes separated by 2 point spaces.

        See also `~.Line2D.set_gapcolor`, which allows those spaces to be
        filled with a color.

            If *seq* is empty or ``(None, None)``, the linestyle will be set
            to solid.
