It can be modified using `.Line2D.set_dashes`. The dash sequence is a series of on/off lengths in points, e.g. ``[3, 1]`` would be 3pt long lines separated by 1pt spaces. Some functions like `.Axes.plot` support passing Line properties as keyword arguments. In such a case, you can already set the dashing when creating the line. *Note*: The dash style can also be configured via a :ref:`property_cycle ` by passing a list of dash sequences using the keyword *dashes* to the cycler. This is not shown within this example. Other attributes of the dash may also be set either with the relevant method (`~.Line2D.set_dash_capstyle`, `~.Line2D.set_dash_joinstyle`, `~.Line2D.set_gapcolor`) or by passing the property through a plotting function. ..
