add_markers_to_lines(ax=None, marker_list=['o', 'D', 's', '+', 'x'], markevery=10)¶
adds markers to existing lings on a plot
this is convinient if you have already have a plot made, but then need to add markers afterwards, so that it can be interpreted in black and white. The markevery argument makes the markers less frequent than the data, which is generally what you want.
- ax (matplotlib.Axes) – axis which to add markers to, defaults to gca()
- marker_list (list of marker characters) – see matplotlib.plot help for possible marker characters
- markevery (int) – markevery number of points with a marker.
