I want to do a double y plot:

plotyy(x,y1,x,y2)
However the x values are not specified in the file thus I just want to plot the y sequences without specifying x. So I am looking for something like:
plotyy(: , y1 , : , y2)

This syntax does not work for course. Is there a way to do this?

Thanks
Fritz

set 

x=1:numel(y)

then use
plotyy(x,y1,x,y2)
