get plotyy second axis handle

I know I can get the second axis handle for plotyy with

[AX,~,~] = plotyy(x1,y1,x2,y2)

and the handle is AX(2) but i use the plotyy function inside another function so AX is deleted because its a local variable

when i use gca (after running the function) in the command window I get what would be AX(1)

So my question is how to get the second axis handle after running the function

Answer 1

[Paulo Silva]

AX=findall(0,'type','axes');
AX(2) %what you are looking for?!

[Zakary Stone]

thanks i tried it and looked about this function and I think this will work for me

[Zakary Stone]

actually using

AX=findall(0,'type','axes')

what i am looking for is

AX(1)

thanks

[Paulo Silva]

You can compare the handles

AX=findall(0,'type','axes');

if AX(1)==gca

MySecondAxes=AX(2)

else

MySecondAxes=AX(1)

end

MySecondAxes %the handle you are interested in (not the current axes)

This also would work:

secondAxes = findobj('Type','axes','Color','none')

[Zakary Stone]

this returns the result that i want but i don't get how it works after reading about it in the help files

but thanks

[Jarrod Rivituso]

no problem. fyi, the reason this works is because plotyy works by creating two axes on top of one another, with the second axes' white background missing. so, you can easily find that second axes by looking for an axes that has it's 'Color' property set to 'none'

[Zakary Stone]

thanks for the explanation

this is exactly what i need(now that i know how it works)

sorry that i already gave the accepted answer check

[Paulo Silva]

All the solutions provided work just fine :)

Answer 3

[Zakary Stone]

thanks for your responses i don't know whether your answers are right or wrong because i am still learning the the program and i'm not familiar with the functions you used

however i after continuing to reading through t help files i found a solution

get(gcf,'children')

this gives me a list of the handles

thanks
