I've been using chartfx 98 from years now without problems. But because of the age of the product I was thinking about upgrading to 6.2. So I downloaded the trial version to start exploring, however, so far, I raised a lot of compatibility issues rendering my applications completely useless. The bottom line would be: Where can I get information about migrating projects from older versions? I have problems with methods, events, and properties that are completely changed. Thanks in advanced.
