title: Matplotlib x-axis overlap
body: <p>I have two lists, x_axis which is list of time in the format of '12:30:00'. The y-axis is percent values. I need to plot all the values on a graph, however since x-axis string is too long they overlap. Is there anyway I can have matplotlib not show every single time on x-axis? Any help would be appreciated.
