Hi Tristan,

Thank you for your quick answer.

Adding the GktPlot to the hierarchy doesn't help much. It just 
suppresses the error messages, but doesn't display anything either.

In fact, I just would like to be able to draw a plot in a drawable 
widget, such as a drawing area. It seems the GtkPlot is not drawable by 
itself (eg. creating a pixmap using plot->window as a reference 
GdkDrawable displays a Gdk error message), thus the idea of using a 
GtkDrawingArea. Maybe I am wrong, please correct me if so.

What I need actually is just a simple example program for plotting data 
in a window, in a simpler way than when using a GtkCanvas.

Thanks
