The original pplus did not have a time-axis style for long time axes like this. We've added a bit of support for such axes but it's not completely flexible.
For plotting, you might want to define a time axis with units of years, but not a calendar time axis. You'll need to take care that you are representing the same times, but here's an example. Say the time axis of the data is monthly from the start of 1940 through October of 1999.
yes? define axis/t=1940.0:1999.833/npoints=718/units=year yearax
yes? let/title="variable title"/units="variable units" my_plot_var = input_var[gt=yearax@asn]
This is not a calendar axis, so Ferret
will NOT translate between the time units as it does for axes
defined with both time units and a time origin. Again, make sure
you're making an equivalent definition, and you have to use the
@ASN transformation to put the data onto this axis, again because
Ferret won't translate between the two.
Now if needed you would use the PPLUS commands such as AXNMTC and AXLINT to adjust tic marks on this axis.

TonyAny other solution? Desperately appreciated!Hi William,Thanks. But this does not work either. It does not control the tics at all.

I tried many ppl commands like TXNMTC, AXNMTC, AXATIC but none works. The tics show up well if I change the window ratio to very wide, though, however I don't like it that way. The automatic setting is annoying here.
