Re: Gdk-WARNING **: gdkgc-win32.c:898: SaveDC failed: Not enough

Hi Prakash,
 Your problem is with gtkplotaxis. GtkPlotAxis is now a GtkObject, so 
all the gtkplotaxis methods have a GtkPlotAxis as first argument. To 
modify an axis in a plot, you should do something like:

GtkPlotAxis *my_axis;

my_axis = gtk_plot_get_axis(plot, GTK_PLOT_AXIS_LEFT);
gtk_plot_axis_set_visible(my_axis, FALSE);
...

The API will freeze after the release, so don't worry about any changes 
hereafter.
Keep me posted, and thank you for the Makefile.
saludos,
<ADRIAN>
