Hi,


I don't know for certain, but it looks like in your loop where you iterate over "num_distinct_markers" and call gsn_add_polymarker(), you are overwriting the variable "dum(j)" each time. There's this comment in the docs for gsn_add_polymarker():

The value returned from this function must be assigned to a unique variable. This is necessary so that the polymarkers "live" for the duration of the NCL script. This is especially imperative if the call to gsn_add_polymarker is inside a function or procedure. Please see the examples section below for more information. 


So I *think* maybe you want dum dimensioned as 3 x num_distinct_markers, and inside the loop the assignment would be:


 dum(j,i) = gsn_add_polymarker(....)


Hope that helps...

Rick

Hi, all


    I want to post some seperate markers in 3 plots and then panel them. However, the markers were not shown correctly
in each sunplots (See the attached wrong.ps,  and the correct subplot was also atteched as the correct_subplot1.ps et al).
I try many time , but can not find a resolution. (the script was also attached). Anyone can give me some help?


Thanks
