Still on GTK+ 2.0.

That's about it.

I'm trying that.   I have signals connected thus;

    g_signal_connect(G_OBJECT(p->canvas), "expose-event",
             G_CALLBACK(&plot_expose_event), p);

    g_signal_connect(G_OBJECT(p->canvas), "select-item",
             G_CALLBACK(&plot_select_event), p);

and get the plot_select_event() routine to calculate and set new canvas 
sizes with

gtk_plot_canvas_set_size(GTK_PLOT_CANVAS(p->canvas), width, height);

then call gtk_widget_queue_resize(GTK_WIDGET(p->table));

This causes plot_expose_event() to get called, which calls 
gtk_plot_canvas_paint(GTK_PLOT_CANVAS(canvas));

But the table rows seem to expand to the largest canvas and don't seem 
to take on variable heights.

Feel I've been around and around the mulberry bush on this ;-)

James.
