Matplotlib 2.x By Example

Choosing markers

There are two groups of markers, unfilled markers and filled_markers.

The full set of available markers can be found by calling Line2D.markers, which will output a dictionary of symbols and their corresponding marker style names. A subset of filled markers that gives more visual weight is under Line2D.filled_markers.

Here are some of the most typical markers:

• 'o': Circle
• 'x': Cross
• '+': Plus sign
• 'P': Filled plus sign
• 'D': Filled diamond
• 's': Square
• '^': Triangle

Here is a scatter plot of random numbers to illustrate the various marker types:

import numpy as npimport matplotlib.pyplot as pltfrom matplotlib.lines import Line2D# Prepare 100 random numbers to plotx = np.random.rand(100)y = np.random.rand(100)# Prepare 100 ...
