axis changing when plotting points

Im plotting data on an axes using GUIDE. I have a loop where I use the plotyy command to plot 2 graphs, one point at a time. I want to set the axis as fixed which I have done, but wanted to do it once before the loop and have it remain.
It didn't work, so I have to reset the desired Y axis range on each iteration of the loop where I plot the data (one point at a time).
Is there a way where I can fix the axis, but still have the data plot one point at a time in a loop (so I can take the axis stuff out of the loop)?
Thanks Jason

You should be able to do this by setting:
set( hAxes, 'YLimMode', 'manual' )
( XLimMode or ZLimMode too if required )
and just set your limits before the for loop. Then they should not change as you plot new points, even if the new points fall outside the visible range.

Perfect Adam, thankyou
Does this work also with things such as markers and colour?
Thanks Jason

Markers and colour are properties of Line objects or whatever you are plotting rather than the axes so I'm not sure what aspect of these you refer to.
By default successive calls to plot will always plot in blue unless you specify the colour yourself.

One method to fix the issue is to place the axis command inside the loop, suppose the limits are :
L=[xmin xmax ymin ymax];
Inside the loop you write :
axis(L)

Thanks Youseff. I was hoping to avoid doing it inside the loop and wanted to see if I could fix it before the loop, yet still plot data inside the loop.
Thanks
