Hello steelxpert
Regarding point 1 (discontinued line chart), I have submitted bug 153401 for this issue.
Regarding point 2, I partially solved the model and upon updating the Line chart (with Perform evaluation for full range' enabled), I am seeing different results at different slider position. Please see a couple of snapshots below showing the line chart at 2 different timings. Can you again cross-check at your end?
