Re: Add markers or curves to existing xy2 plot array

Hi Karin,

Thank you very much for your help.

I mean on my left axis it is temperature, on the same plot but right axis
it is pressure.
I want to add temperature markers to the left axis and pressure markers to
the right axis.

If my plot is scalar, it is easy. just:
dum1 = gsn_add_polymarker(wks,plot,x,temperature,res1)
dum2 = gsn_add_polymarker(wks,*plot@xy2*,x,pressure,res1)

But if plot is an array, I don't how to do it.
I will write a sample script today.

Thank you!

Best,
Wenshan
