[ncl-talk] Question about gsn*String positioning with gsn_csm_x2y2 routine

[Mary Haley]

Hi Alex,

There's a short answer and a long answer.

The short answer is to try setting "res at pmTitleZone" resource to either 1,
2, 3, or maybe 4.

The long answer is that NCL's PlotManager uses "zones" to try to determine
where to place titles with respect to the plot. I think zones 0 and 1 are
contained within the plot X/Y axis boundary, zone 2 is just outside the
plot, for example, where the tickmarks are, zone 3 is the area containing
the tick mark labels, and so on.  The x2y2 routine is assuming that the top
tickmarks and labels are all on, so it sets pmTitleZone to either 4 or 5,
which causes the title to be moved up. By setting it to a lower value, this
causes the title to move down.

If you want to read some exciting stuff on zones, see:

I've created a ticket for this, NCL-2470.
