Linestyles#

Simple linestyles can be defined using the strings "solid", "dotted", "dashed" or "dashdot". More refined control can be achieved by providing a dash tuple (offset, (on_off_seq)). For example, (0, (3, 10, 1, 15)) means (3pt line, 10pt space, 1pt line, 15pt space) with no offset, while (5, (10, 3)), means (10pt line, 3pt space), but skip the first 5pt line. See also Line2D.set_linestyle.

Note: The dash style can also be configured via Line2D.set_dashes as shown in Customizing dashed line styles and passing a list of dash sequences using the keyword dashes to the cycler in property_cycle.
