Hi there, say, I have x and y data like this (the real data I am working with is from numerical simulations, though):
from numpy import arange, sin x = arange( 0., 1., 0.001 ) y = sin( 50*x ) Now, a line plot would not look very decent because of the 1000 overlapping markers: plot(x, y, '-ro') Now, I'd rather have the same plot with a marker symbol only every 20th data point. Of course, I can easily achieve this by slicing through my data set and making two plots, one for the line and another one for the markers: line = plot(x, y, '-r') markers = plot(x[::20], y[::20], 'ro') Note that just doing a plot(x[::20],y[::20],'-ro') would 'distort' the plot because the markers are being linked by straight lines. What fails me is how to make a legend with the appropriate 'combined' line style '-ro'? I have tried to supply the legend statement with that linestyle: legend( ['-ro'], ['data'] ) but it really expects a list of line instances, so that did not work.
