Matplotlib: Don't show errorbars in legend

Question

I'm plotting a series of data points with x and y error but do NOT want the errorbars to be included in the legend (only the marker). Is there a way to do so?

Example:

import matplotlib.pyplot as plt import numpy as np subs=['one','two','three'] x=[1,2,3] y=[1,2,3] yerr=[2,3,1] xerr=[0.5,1,1] fig,(ax1)=plt.subplots(1,1) for i in np.arange(len(x)):     ax1.errorbar(x[i],y[i],yerr=yerr[i],xerr=xerr[i],label=subs[i],ecolor='black',marker='o',ls='') ax1.legend(loc='upper left', numpoints=1) fig.savefig('test.pdf', bbox_inches=0)

You can modify the legend handler. See the legend guide of matplotlib. Adapting your example, this could read:

import matplotlib.pyplot as plt import numpy as np  subs=['one','two','three'] x=[1,2,3] y=[1,2,3] yerr=[2,3,1] xerr=[0.5,1,1] fig,(ax1)=plt.subplots(1,1)  for i in np.arange(len(x)):     ax1.errorbar(x[i],y[i],yerr=yerr[i],xerr=xerr[i],label=subs[i],ecolor='black',marker='o',ls='')  # get handles handles, labels = ax1.get_legend_handles_labels() # remove the errorbars handles = [h[0] for h in handles] # use them in the legend ax1.legend(handles, labels, loc='upper left',numpoints=1)   plt.show() 

This produces
