[ncl-talk] text res

[Mary Haley]

Geeta,

I'm not sure what you mean by "messy".

You are setting txPosXF and txPosYF, but these resources are meaningless,
because the "gsn_add_text" function has the X and Y positions as part of
its argument list, in your case, the "lon" and "lat" arguments:

  text  = gsn_add_text(wks,plot,sprintf("%9.4g",rf),lon,lat,txres)

So, you should be trying to change your lon and lat values, and not txPosXF
and txPosYF.

If by "messy" you mean that the text string is touching the markers in a
couple of places, then there are several things you can do.

One is to simply add some extra spaces before the text strings. You can do
this by changing the format in the "sprintf" call to have more fields:

  text  = gsn_add_text(wks,plot,sprintf("%11.4g",rf),lon,lat,txres)

or by adding a space:

  text  = gsn_add_text(wks,plot,"  " + sprintf("%9.4g",rf),lon,lat,txres)

You can also add a small delta value to the "lon" position:

  text  = gsn_add_text(wks,plot,sprintf("%9.4g",rf),lon+0.1,lat,txres)
