Hi @ConradG,
Bubble Plot animation currently works on the time levels [0, n-1], and not directly on the time values. Since you have regularly spaced data, it should be possible to get close to what you want, so I'll describe what JMP is doing.
Animation speed is controlled by changing two factors:
- A delay between each frame (from 1-60 frames/sec)
- The increment in time level between each frame
At the default speed (10):
- A frame is shown every 1/15s
- Time advances by .1 levels between each frame shown
With constantly spaced time, you should see time advance at roughly 1.5 levels/sec. Changing the speed will have a linear effect (up to the min/max), so if you want to advance at n levels / sec you can use speed = n*20/3.
I tried this with the PopAgeGroup sample data in the attached file PopAgeAnimationSpeed.jsl. It seems to be very close to the intended result, but there are double->int conversions as part of the process that might affect the results slightly. I would be interested in hearing about how closely this matches the desired effect for your data.
