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 :doc:`property_cycle ` by passing a list of dash sequences using the keyword *dashes* to the cycler. This is not shown within this example. .. image:: /gallery/lines_bars_and_markers/images/sphx_glr_line_demo_dash_control_001.png :class: sphx-glr-single-img .. code-block:: python import numpy as np import matplotlib.pyplot as plt x = np.linspace(0, 10, 500) y = np.sin(x) fig, ax = plt.subplots() # Using set_dashes() to modify dashing of an existing line line1, = ax.plot(x, y, label='Using set_dashes()') line1.set_dashes([2, 2, 10, 2]) # 2pt line, 2pt break, 10pt line, 2pt break # Using plot(..., dashes=...) to set the dashing when creating a line line2, = ax.plot(x, y - 0.2, dashes=[6, 2], label='Using the dashes parameter') ax.legend() plt.show() .. _sphx_glr_download_gallery_lines_bars_and_markers_line_demo_dash_control.py: .. only :: html .. container:: sphx-glr-footer :class: sphx-glr-footer-example .. container:: sphx-glr-download :download:`Download Python source code: line_demo_dash_control.py ` .. container:: sphx-glr-download :download:`Download Jupyter notebook: line_demo_dash_control.ipynb ` .. only:: html .. rst-class:: sphx-glr-signature Keywords: matplotlib code example, codex, python plot, pyplot `Gallery generated by Sphinx-Gallery `_
