 Depending on how gnuplot is plotting the data, more than one value may be needed
-to represent a single point. For example, the script has support to plot all the
-data with C<--circles>. This requires a radius to be specified for each point in
-addition to the position of the point. Thus, when plotting with C<--circles>, 2
-numbers are read for each data point instead of 1. A similar situation exists
-with C<--colormap> where each point contains the position I<and> the color.
-There are other gnuplot styles that require more data (such as error bars), but
-none of these are directly supported by the script. They can still be used,
-though, by specifying the specific style with C<--style>, and specifying how

+More examples: if making a 2d plot of y error bars where gnuplot expects a
+(x,y,ydelta) tuple for each point, you want C<--rangesizeall 2> because you have
+one domain value (x) and 2 range values (y,ydelta). Gnuplot can also plot
+lopsided y errorbars by giving a tuple (x,y,ylow,yhigh). This is similar as
