Re: [ferret_users] too many tics

[William Kessler <william.s.kessler@xxxxxxxx>]

Two solutions:

1) Include a 3rd argument to HLIMITS, VLIMITS to specify the intervals:

plot/vlimits=-5500:0:500/y=30S/hlimits=111:115:0.5 rose  ! large/main tics every 500m and 0.5 deg

2) Use PPL AXLINT (label interval for large tics) and PPL AXNMTC (number of small tics between large tics)

plot/SET/vlimits=-5500:0:500/y=30S/hlimits=111:115:0.5 rose
ppl axlint,2,2;ppl axnmtc,4,4  ! label every 2nd large tic; add 4 small tics between large tics
ppl plot

Notes:
- the PPL commands are persistent until explicitly changed
- PPL AXLSZE,xlab,ylab    controls the label size
- Could also control the label format (decimal point):
- PPL XFOR,(i5,''lone'')   ! those are two single quotes around LONE = longitude east
  Or, if, say the half-degree tics are to be labelled: PPL XFOR,(f5.1,''lone'')
- PPL YFOR,(i5)   ! integer labels with length to fit -5400
