Thanks, i have another problem.
In the VI enclosed i have a listbox of URLs. My goal is that each time i press on an element on the listbox i get a new plot in the graph XY(corresponding to theURL); but i want that the properties of a plot (color, style) remain for the same plot but each time i choose an element i see the properties of a plot transfered to the new plot.
Could u tell me where is the problem in my VI ?
Samer,
