Re: Add markers or curves to existing xy2 plot array

Hi Karin,

Which one exactly do you mean?
Sorry I didn't see any one that can solve my problem here.

Let me see if I can explain my situation better.
I have several panels on one page. On each panel, the XY plot has two
different y-axes.
I use:
do i = 0, n
    plot(i) = gsn_csm_xy2(...)
end do

Then I want to add markers to each panel on both y-axes.
Basically, I want something like
1 do i = 0, n
2 plot(i) = gsn_csm_xy2(...)
3 dum_left(i) = gsn_add_polymarker(wks, plot(i), x, y1, res1)
4 dum_right(i) = gsn_add_polymarker(wks, *plot(i)@xy2*, x, y2, res2)
5 end do

but of course, line 4 is not right in syntax.
I was wondering whether there is a way to do so.

Thank you very much for your time!

Best,
Wenshan
