combomarginsplot (two y axis)

[Said Kaawach]

Hello Everyone,

I hope someone would be able to help me with the following:

I have this code:

    eststo: reghdfe Man2Auto l.sharpe_ratio l.PercentAutoBid l.c.PercentAutoBid#l.c.PercentAutoBid ///
    l.c.sharpe_ratio#l.c.PercentAutoBid l.c.sharpe_ratio#l.c.PercentAutoBid#l.c.PercentAutoBid, a(LenderId hour LoanId) cluster(interaction)
            estadd local LenderId "Yes", replace
            estadd local hour "Yes", replace
            estadd local LoanId "Yes", replace

    est store AutoSwitching
    nlcom -_b[l.PercentAutoBid]/(2*_b[l.c.PercentAutoBid#l.c.PercentAutoBid])
    margins,at(l.PercentAutoBid = (0(0.1)1)) saving(file1, replace)
    margins,dydx(l.sharpe_ratio) at(l.PercentAutoBid = (0(0.1)1)) saving(file2, replace)
    
    combomarginsplot /*
    */ file1 file2, plot1opts(lc(black) lp(longdash_dot)) ciopt(color(black)) plotopts(mcolor("black")) /*
    */ labels("Share Auto Bidding" "Sharpe Ratio") xline(.786, lstyle(grid) lp(longdash_dot) lc(maroon)) xti("Share Auto Bidding") /*
    */ text(0.04 0.77 "Turning Point at 0.786", place(s) orient(vertical) color(black) size(small)) /* 
    */ yti("Probability") name(plot1, replace)

The figure I produce is okay, except for an issue with the Y-axis. It generates a Y-scale between -0.4 and 0.4, which is suitable for the 'sharpe_ratio' which is great.
However, I also want to add another Y-scale on the right side for 'PercentAutoBid', with a range from 0 to 0.15. The problem with the current version of the figure is that the scale of sharpe_ratio is larger than PercentAutoBid. PercentAutoBid shows non-linear relationship If I plot it on its own.
But when I plot it with sharpe_ratio, the scale of PercentAutoBid is much smaller and it looks just looks different (more like a straight line).

Thank you in advance.

If anyone knows how to add another Y-axis to a combomarginsplot, could you please guide me?

Any help is appreciated.

Thanks
