10.4
Unfortunately there are some underlying differences that mean that the 10.4 version does not work properly in 10.5. The differences are minor, but enough that DataGraph has two versions, one for 10.4, the other for 10.5. If you run the 10.4 version in 10.5, you will get a notification that you should update to the 10.5 version.
