Hi all, We would like to extend VisAD, in order to change axes'depiction, like having a label for each graduation. We tough of extending the ScalarMap class, in order to overide the method makeScale that builds scales. But most attributs and methods are private or have package privacy, we can't then inherit it in another package. Is there another way to modify axis depiction, or can some attributs of the ScalarMap class become protected? thanks louise PS: thanks to all people who participate in making VisAD. It is a great tool.
