Fixed bug in default plot for FrequencySeries
This PR fixes #412 (closed) by improving the default formatting of log axes on a FrequencySeriesPlot
. The trick is to set the x-axis scale (ax.set_xscale
) before setting the limits.
This PR also modifies the test_plot
method for all of the class tests to include a plot.save
operation to make sure that the default figure actually renders (which would have caught #412 (closed)).
