Is matlabs automatic axis limit function available?

Hi.
I am writing a custom plotting function, and one of the most difficult things to implement is the function that takes the range of the input data and sugests the axis limits and the tick spacing. Does anyone know if it is possible in some way to access matlabs such built-in function?

Sincerely
Daniel Armhyr

Something like this?

x = 100*rand(3,1) ;
y = 100*rand(3,1) ;
tempaxes = axes('position',[0 0 1 1],'visible','off') ;
plot(x,y) ;
suggestedXlimits = get(tempaxes,'xlim')
% and other properties
delete(tempaxes)

Well, yeah, pretty much. The "Visibility off" trick was nifty. But this is really a very, very ugly hack. I had hoped for something a bit prettier. But for now, it will probably do ver well.

Thank you very much.

I agree it's ugly, but wrap it inside a function with a nice name and you'll never know ;-)
