<p>Hello Adrian,<o:p></o:p></p>
<p>Here is what I would do:<o:p></o:p></p>
<p>(1) use 'tag' property field of your curve together with findobj to get access to the plot to be updated, without passing the handle.<br>
(2) instead of deleting the curve and recreating it, I would directly modify its content (data property) and then ask for a replot/rescale if needed.<o:p></o:p></p>
<p>You can have a look at the content of function 'replot()' for a typical example.<br>
It get called when the user changes the top slider in the GUI or presses Re-run.<br>
It is far from perfect, but it does something that might look like what you want.<o:p></o:p></p>
<p>Hope it helps,<o:p></o:p></p>
<p>Antoine<o:p></o:p></p>
