 --------------------
 Specify the plot range. By default the range is chosen such that all data
-is visible in linear plots. In logarithmic plots the automatic choice of `YMin`
+is visible in linear plots, and the zero is visible. `ShowZero=0` suppresses
+plotting the zero in linear plots and thus zooms into the actual y-value range
+of the distribution. In logarithmic plots the automatic choice of `YMin`
 is limited to be not smaller than 2e-4*`YMax`, but manually you can specify
 any value. `FullRange=1` also overrides the 2e-4*`YMax` limit and plots the
 full range in y.
