Re: [ferret_users] plot only one color bar for all viewports

Dear Xiaoyu

G'day

If I understood you correctly, then here is an example to use multi_view in Pyferret (https://github.com/NOAA-PMEL/Ferret/blob/master/jnls/contrib/multi_view.jnl)

!!!!! example of 4 rows and 4 columns !!!!!!!!!!!!!

go multi_view 4,4,.2185,0.052,0.012,.18,.095,0.048,a

!!!!! putting a common shade key or colour key below the panel in the 4th row and 1st column (https://ferret.pmel.noaa.gov/Ferret/faq/modifying-the-shade-key) for the Variable named "VAR"

set viewport a41

fill/nokey/set/lev=(-inf)(-2,2,.4)(inf)/nolab/palette=orange_blue VAR
ppl shakey 1, 0, 0.20, , 6, 6, 1.2, 7.3, .30, .47
ppl fill

I hope this helps. Let us know if it doesn't work the way you want. 

Cheers, Saurabh

Dear ferreters,

I have 10 viewports of precipitation difference that all have similar but not the same levels (say levels=(-90,90,10) and levels=(-80,80,10)). It will be too noisy if I have 10 colorbars and I want the shading color to be the same for the same value (say red for -90 and blue for 90 no matter what my levels are). So I tried to plot only one shakey by setting view full after plotting all the subplots. Then I used ppl shakey and figured that Pyferret cannot find any shakeys because it already quit all the viewports. I am wondering if there is a way to create a shakey that works for all viewports (picking one viewport's shakey does not work for me because my levels are not all the same so the shakey will not be accurate, as attached).  

Thank you in advance and stay healthy,
