[SOLVED] QWT Plot refresh

[toho71]

Hello.
I'm using the QWT plot to show some graphs in my application and it works fine.
The problem is to make an auto refresh and clear the plot area from the old plots before I start drawing the new plots again.
I have tried the auto delete, autoreplot and repaint methods but no success.

I dont find a clear method in the class references either.

Is there an easy way to solve this minor problem,

Solution is detachItems()
