Thread: [Matplotlib-users] Setting dash size and gap of dashed line in matplotlib

hi all,

I am plotting certain dashed lines in matplotlib, using:

plt.plot(x, y, '--')

I'd like to set the dash size (i.e. length of each dash) and the gap
between the dashes of the plotted line. Is there a way to set this
from matplotlib?

thanks.

plt.plot([0,1], [2,3], '--', dashes=(10,20))

The dashes kwarg sets a Line2D parameter. See
