Re: [ferret_users] Removing minor tic marks from time axis plots

[Ansley Manke <ansley.b.manke@xxxxxxxx>]

Hi -
I have just a couple of comments to add to Billy's answer. For these ppl 
commands which customize plotting, x means the horizontal axis, and y 
the vertical axis. So for this time series plot, you could do the 
following to change the tics on the horizontal axis and leave the tics 
on the vertical axis as they are.

  plot/set myvar
  ppl tics,0,0.25
  ppl plot

If you're doing overlays, the first plot command is the one that draws 
the axis, so the overlay commands don't need the addition of PPL commands.
