Markers
You can use the keyword argument marker to emphasize each point with a specified marker:
Example
import matplotlib.pyplot as plt
import numpy as np
ypoints = np.array([3, 8, 1, 10])
plt.plot(ypoints, marker = 'o')
plt.show()Example
...
plt.plot(ypoints, marker = '*')
...Format Strings fmt
You can also use the shortcut string notation parameter to specify the marker.
This parameter is also called fmt , and is written with this syntax:
Example
import matplotlib.pyplot as plt
import numpy as np
ypoints = np.array([3, 8, 1, 10])
plt.plot(ypoints, 'o:r')
plt.show()The marker value can be anything from the Marker Reference above.
The line value can be one of the following:
Marker Size
You can use the keyword argument markersize or the shorter version, ms to set the size of the markers:
Example
import matplotlib.pyplot as plt
import numpy as np
ypoints = np.array([3, 8, 1, 10])
plt.plot(ypoints, marker = 'o', ms = 20)
plt.show()Marker Color
You can use the keyword argument markeredgecolor or the shorter mec to set the color of the edge of the markers:
Example
import matplotlib.pyplot as plt
import numpy as np
ypoints = np.array([3, 8, 1, 10])
plt.plot(ypoints, marker = 'o', ms = 20, mec = 'r')
plt.show()You can use the keyword argument markerfacecolor or the shorter mfc to set the color inside the edge of the markers:
Example
import matplotlib.pyplot as plt
import numpy as np
ypoints = np.array([3, 8, 1, 10])
plt.plot(ypoints, marker = 'o', ms = 20, mfc = 'r')
plt.show()Use both the mec and mfc arguments to color the entire marker:
Example
import matplotlib.pyplot as plt
import numpy as np
ypoints = np.array([3, 8, 1, 10])
plt.plot(ypoints, marker = 'o', ms = 20, mec = 'r', mfc = 'r')
plt.show()You can also use Hexadecimal color values :
Example
...
plt.plot(ypoints, marker = 'o', ms = 20, mec = '#4CAF50', mfc = '#4CAF50')
...Or any of the 140 supported color names .
Example
...
plt.plot(ypoints, marker = 'o', ms = 20, mec = 'hotpink', mfc = 'hotpink')
...
