Hi Adam,
Thank you for your suggestions.
I followed your 2nd method and able to overlap the 2 set of plots.
But I am unable to control the viewport and as a result the plots are not exactly overlapped.
I used vpWidthF and vpHeightF as 0.8 and 0.2 respectively for both the panels.
But the plots at 2nd panel are appeared larger than that of the 1st panel.
The gsnPanelDebug for 1st panel are as follows:
plot #0
(0) new x,y = 0.381421,0.993689
(0) orig wdt,hgt = 0.8,0.2
(0) new wdt,hgt = 0.265712,0.0664279
(0) -------Panel viewport values for each plot-------
(0) plot #1
(0) new x,y = 0.381421,0.914572
(0) orig wdt,hgt = 0.8,0.2
(0) new wdt,hgt = 0.265712,0.0664279
(0) -------Panel viewport values for each plot-------
(0) plot #2
(0) new x,y = 0.381421,0.835455
(0) orig wdt,hgt = 0.8,0.2
(0) new wdt,hgt = 0.265712,0.0664279
(0) -------Panel viewport values for each plot-------
(0) plot #3
(0) new x,y = 0.381421,0.756338
(0) orig wdt,hgt = 0.8,0.2
(0) new wdt,hgt = 0.265712,0.0664279
(0) -------Panel viewport values for each plot-------
(0) plot #4
(0) new x,y = 0.381421,0.677221
(0) orig wdt,hgt = 0.8,0.2
(0) new wdt,hgt = 0.265712,0.0664279
(0) -------Panel viewport values for each plot-------
(0) plot #5
(0) new x,y = 0.381421,0.598104
(0) orig wdt,hgt = 0.8,0.2
(0) new wdt,hgt = 0.265712,0.0664279
Should I use vpXF and vpYF for the 2nd panel?
Or should I use same vpXF and vpYF for both the panels?
What will be their values for the plots at the 2nd panels?
Please let me know the same.
Regards,
Abhik

Subject: Re: Overlay is not working
Hi Abhik,
It looks like you are trying to overlay a XY plot onto a spatial map
plot. I would venture to guess that NCL isn't sure how to overlay the 2,
as the plot types are completely different.
Someone might have a better alternative, but I see two possibilities:
1) Create all 6 map plots, call gsn_panel (but don't advance the frame
by setting gsnFrame = False in the Panel resource list), create all 6 XY
plots, call gsn_panel, manually advance the frame. You may have to
adjust the vpWidthF/vpHeightF resources for the XY plots, and you will
likely have to set gsnPanelXWhiteSpacePercent,
gsnPanelYWhiteSpacePercent, gsnPanelBottom,gsnPanelTop,gsnPanelRight and
gsnPanelLeft in the Panel resource lists to try to get things lined up
correctly.
2) First create all 6 map plots, call gsn_panel (but don't advance the
frame by setting gsnFrame = False in the Panel resource list). Draw each
XY plot individually, exactly specifying the placement over each of your
6 map plots via the vpXY/vpYF resources. In this scenario you will want
to set gsnFrame = False in the xy resource list, and at the end of the
script call frame(wks)..
I'd recommend trying method 2 first, as even though that method is more
tedious than the 1st method, you have a higher chance of lining things
up exactly as you want them..
If you have further questions about this issue please respond to ncl-talk.
Good luck,
Adam
