Re: [ferret_users] How to make a plot with 2 Y axis

[Olivier Marti <olivier.marti@xxxxxxxxxxxx>]

The solution is to define two viewports with the exact same parameters : same location, same margins.

I can send you a go file that duplicate a viewport.

Hi all,

I’m trying to make a plot with 2 time series, each on a separate Y axis (one on the left side and one on the right side of the plot).

I’ve tried left_axis_plot and right_axis_plot.

also tried multi_yaxis_plot1 and multi_yaxis_overlay.

Nothing really works well as I can’t find the way to get the 2^nd Y axis at the right side of my plot. It’s either on the left of the main axis  (using “-“ for  multi_yaxis_overlay), or it’s just at the right of the left plot, ie in the middle of the figure ! (“+” for  multi_yaxis_overlay, see screenshot)

 

Also I don’t know how to control the format of the axis anymore (ppl xfor, yfor, etc…).

 

I can send my data but essentially, it’s two time series. For example:

DEFINE AXIS/T=2021:2030:1/UNIT=year tax

DEFINE GRID/T=tax my_grid

SET GRID my_grid

Var1 = 500 - 50*(T-2020)

Var2 = 25/(10-(T-2020))

 

Thanks for any help.

Pierre
