I have been used Origin under Windows for years until two years ago I converted to Mac OSX. It has been a headache to find a graphing tool under Mac that is both easy to use and powerful, like Origin. Then I find this one is a potential solution for me, as the author tries to mimic Origin for Mac.
So far the only problem for me is that it does not export EPS file correctly, as well as a few glitches. But I'm confident the author will improve the functionality as it turns to version 1.0.
Thanks for good work!!
