[ncl-talk] dimension size mismatch when using gsn_add_text

[Anne]

Hello NCL users,

I am trying to add a label to my xy plot using the routine gsn_add_text.
However this causes a 'dimension size mismatch' error message. I don't
really understand why this would be a mismatch because I haven't defined
this variable anywhere else in the script.

So I used:

plot0  = gsn_csm_xy (wks, years2, var_diff(:,month),res)


    txres               = True
    ;txres at txFontHeightF = fheight             ; Set the font height
    txres at txJust        = "CenterRight"
    txres at txFontHeightF   = 0.014

                 label                    = "Mean response =
"+var_ens_diff_mean+""
                 text = gsn_add_text(wks, plot0, label, 1994, -100, txres)

 plot1  = gsn_csm_xy (wks, years, var_ens_diff(:,month), res)

         overlay(plot0, plot1)

        draw(plot0)
        frame(wks)

So basically this is an overlaid xy scatter plot, and I've applied my label
to the base plot (plot0). The error message that shows up refers to the
line where gsn_add_text is used (text = ...). Both the x and y coordinates
in gsn_add_text are coordinates as they appear in the plot, so this
shouldn't cause a problem.

Thanks for any help,
Anne
