[ncl-talk] String in x axis (XY plot)

[Karin Meier-Fleischer]

Hi John,

You can't use your date variable in the gsn_csm_xy function call because 
date
is of type string, not numeric.
You have to set explicit values and levels for the bottom x-axis like below

   xvalues = ispan(1,dimsizes(date),1)

   res at tmXBMode              = "Explicit"            ;-- y-axis draw mode
   res at tmXBValues            = *xvalues*      ;-- use pre-defined values
   res at tmXBLabels            = *date*     ;-- use pre-defined labels
   res at tmXBLabelAngleF       =  50.0
   res at tmXBLabelDeltaF       =   1.5
   res at tmXBLabelFontHeightF  =   0.009
   res at tmXBLabelJust         = "CenterRight"

   plot  = gsn_csm_xy(wks,*xvalues*,data(:,6),res)

Bye,
Karin
