Matplotlib 2 lines with different markers - medatib531 - Sep-15-2020
Hello,
I want to create a matplotlib plot for 2 different lines, however I need the lines to have different markers.
i.e. use 'x' as marker for line 1 and '^' as marker for line 2.
I tried to use itertools.next() as I saw in some online suggestions but no luck, plot still appears with 'x' as marker for both lines. Can someone help?
My MWE code and the resulted plot below:
from matplotlib import pyplot as plt
import itertools
xlist = [5, 10, 15, 20, 25]
ylist = [[0.260864, 0.238644], [0.514823, 0.473904], [0.764035, 0.714735], [1.021157, 0.950179], [1.2735940000000001, 1.186469]]
labelList = ["Line1","Line2"]
fig, ax1 = plt.subplots()
markers = itertools.cycle(['x','^','v'])
ax1.plot(xlist,ylist,linewidth=1,marker=next(markers))
ax1.set_xlabel('x axis')
ax1.set_ylabel('y axis')
plt.legend(labelList)
plt.show()![[Image: l25X4n4.png]](https://i.imgur.com/l25X4n4.png)
Solution:
from matplotlib import pyplot as plt
import itertools
xlist = [5, 10, 15, 20, 25]
ylist = [[0.260864, 0.238644], [0.514823, 0.473904], [0.764035, 0.714735], [1.021157, 0.950179], [1.2735940000000001, 1.186469]]
labelList = ["Line1","Line2"]
fig, ax1 = plt.subplots()
markers = itertools.cycle(['x','^','v'])
ax1.plot(xlist,[item[0] for item in ylist],linewidth=1,marker=next(markers))
ax1.plot(xlist,[item[1] for item in ylist],linewidth=1,marker=next(markers))
ax1.set_xlabel('x axis')
ax1.set_ylabel('y axis')
plt.legend(labelList)
plt.show()
