[ncl-talk] Modifying a boxplot diagram's x-axis

[Alan Rhoades]

Hi Adam,

Thanks for the prompt reply!  The description of the @boxWidth command was
very helpful.

I am still curious if there is a possible way to push all of the x-axis
labels closer together, maintain the x-axis label font size, and thus
eliminate the physical gaps, rather than simply filling in the space with
the boxplot lines via @boxWidth?  It seems that no matter what value you
scale the x-axis to (i.e., 1 to 15 by 1, or 0 to 1 by 1/15) the space on
the plot image is still maintained on the x-axis and "awkward" spacing is
still seen between the x-axis tickmark labels.

All the best,

AR
