Remove line through marker in matplotlib legend
You can specify linestyle="None" as a keyword argument in the plot command:
import matplotlib.pyplot as pyplotFig, ax = pyplot.subplots()for i, (mark, color) in enumerate(zip( ['s', 'o', 'D', 'v'], ['r', 'g', 'b', 'purple'])): ax.plot(i+1, i+1, color=color, marker=mark, markerfacecolor='None', markeredgecolor=color, linestyle = 'None', label=`i`)ax.set_xlim(0,5)ax.set_ylim(0,5)ax.legend(numpoints=1)pyplot.show()
Since you're only plotting single points, you can't see the line attribute except for in the legend.
You can set the rcparams for the plots:
import matplotlibmatplotlib.rcParams['legend.handlelength'] = 0matplotlib.rcParams['legend.numpoints'] = 1
All the legend.* parameters are available as keywords if you don't want the setting to apply globally for all plots. See matplotlib.pyplot.legend documentation and this related question:
legend setting (numpoints and scatterpoints) in matplotlib does not work
To simply remove the lines once the data has been plotted:
handles, labels = ax.get_legend_handles_labels()for h in handles: h.set_linestyle("")ax.legend(handles, labels)
