I have a programme that draws a chart in a drawingarea using paint.begin etc.
How can I clear the drawingarea for a different form of chart.
drawingarea.clear doesn't do it and I can't see a paint method.

Also,is there a convenient way to print the drawingarea image to a printer?

Any advice would be appreciated

Have a look at the attached example that draws and clears a DrawingArea.

Have a look at ChartExample in the Gambas Farm, that uses a DrawingArea but no drawing is needed.

I'm not sure about printing yet!

Let us know how you get on.

Unfortunately it doesn't tell you how to print the contents of a DrawingArea.

As you paint to the DrawingArea you simultaneously draw to the printer, or you can draw to an image, and draw the image to the drawingarea and the printer...

And on a side note:
With cairo you can even draw to PDF or SVG: /comp/gb.cairo - Gambas Documentation

I suggest this Wiki page of italian forum:

Stampare il contenuto di una DrawingArea - Gambas-it.org - Wikipedia

Thanks for all the suggestions - am happily printing and modifying drawing area
