Matplotlib Tutorial #6: Plot Line Customization

#beginners #datascience #tutorial #python

In previous blog I have explained how to customize a marker in Matplotlib plot, in today's blog I will show you how to customize a line in plot.

Line Style

You can use the keyword argument linestyle, or shorter ls, to change the style of the plotted line. linestyle can have values of:

- or solid to have a solid line, this is the default style of line of you don't specify it.
: or dotted to have a dotted line.
-- or dashed to have a dashed line.
-. or dashdot to have a dashdot line.
'' or None to have a plot with no line.

The following is the implementation of Matplotlib linestyle customization

import matplotlib.pyplot as plt
import numpy as np

ypoints = np.arange(10)

plt.plot(ypoints, linestyle='--')
plt.show()

The following is the output of the above code

You can use the keyword argument linewidth or the shorter lw to change the width of the line

import matplotlib.pyplot as plt
import numpy as np

ypoints = np.arange(10)

plt.plot(ypoints, linewidth=20)
plt.show()

You will get the following output

There you go, that is how you can customize line in Matplotlib plot. Thank you for reading this blog, and have a good day!
