GtKplot

Hi evrybody, I also had some problems posting on the list. I hope you'll get my message since all my former messages received an error ! I'm currently working with GtkPlot and I encoutered a few problems which I hope someone will solve :) - first of all when the range of the graphic is too important, the labels on the axes mess with each other and we cannot see anything at all ! How can I set the step of the axis labels ? - next, I'd like to add two curves to the graph, but the first one doesn't display, only a few points on the Y axis. Does anyone know how to get rid of this ? - GtkPlotData::set_points takes 5 arguments, the X values, the Y values, something, something, and the number of points to display. As you will have guessed, what are something and something ? Thanx a lot if you can help :) Bye, Jonathan
