If a colormap like this was used in a plot and then the plot was printed to grayscale, a lot of the information may map to the same gray values. randn(100,5)) ax = df. If False, markers are plotted at the xcorr values using Axes. distance must be defined in meters (Default). I spent a while working through this and found that the best method was to reassign the data and plot with matplotlib instead of the built in obspy module plotters, as they are designed more as 'preview' panes than as final figures. We highly recommend and only officially support the latest release of each series.
