Hello,
i am trying to plot two ASCII files on the same window , each file has two
column data.
due to the difference of the dimension in two files ,i have used the
interface gsn_csm_x2y2
but i still have the following error
* (0) gsn_csm_xy: Fatal: X and Y must have the same dimensions sizes, or one
must be one-dimensional and both have the same rightmost dimension.*
*warning:TransInitialize: Zero Y coordinate span: defaulting:[errno=1104]*
*(0) gsn_csm_xy: Fatal: X and Y must have the same dimensions sizes, or one
must be one-dimensional and both have the same rightmost dimension.*
*warning:TransInitialize: Zero Y coordinate span: defaulting:[errno=1104]*
here is the ncl file

begin
data_jacopi = asciiread("jacopi.error",(/584,2/),"float")
data_gauss = asciiread("gauss.error",(/301,2/),"float")
x_jacopi = data_jacopi(:,0)
y_jacopi = data_jacopi(:,1)
x_gauss = data_gauss(:,0)
y_gauss = data_gauss(:,1)
;**************************************************

res1@tiMainString = "relaxation error" ; title

res1@xyLineColor = (/"red"/) ; control the line colors.
res2 = True
res2@trXMinF = min(x_gauss)
res2@trXMaxF = max(x_gauss)
res2@trYMinF = min(y_gauss)
res2@trYMaxF = min(y_gauss)
wks = gsn_open_wks("x11","gsn_xy") ; Open an ps workstation.
; plot = gsn_csm_xy(wks,x_jacopi,y_jacopi,res) ; Draw an XY plot with 1
curve.
plot = gsn_csm_x2y2(wks,x_jacopi,y_jacopi,x_gauss,y_gauss,res1,res2)
end
~
i have attached the data files
thanks in advance
