[Nplot-devel] Log-Log Plots and Major-Minor Grids, and Number Formats

[Edward B. P. <phi...@ho...>]

Can someone send me an examples or modification to the code below to show
how to place Major and Minor Grids lines on a Log-Log plot.
I can get Major, but the minors are not showing up.  Also how to get the
format of the numbers on the major ticks to be in 0.0E+00 format.
One last item  the last number on the x-axis labels is being cut-off a
little how do I fix this.
