Description:

Would it be possible to override a method this way?

sub GD::Graph::axestype::create_x_label {

or \&GD::Graph::axestype::create_x_label = sub { I know these doesnt work because I've tried, is there another way like this?

Answer: overriding a methods.

The first one works fine, provided you understand that you're compiling code which has to be compiled after the original method is compiled. So, it's fine after a use that pulls in the other module. You'll probably get a "redefining ___" warning though. The typeglob assignment has also worked for me in the past.

You could typeglob...

*GD::Graph::axestype::create_x_label = sub {...}
