I'm confused - you did try the logical thing of doing this twice - once for the 2 sets of x-vals and once for the 2 sets of y-vals?

I haven't yet used GD::Graph, but the syntax you gave seems to imply that

my @graph_data = (\@x_vals, \@y_vals)
is the expected format. So...
@x_vals = (@x_vals1, @x_vals2); @y_vals = (@y_vals1, @y_vals2); my @graph_data = (\@x_vals, \@y_vals);

If this isn't the solution, then you'll have to wait for someone who knows perl and/or GD::Graph better than me...
