I have abandoned the Maple DAE events handling. I'm happy with the attached demo. About the curve features listed in Stuart suggestion, this work sheet is a good example to appreciate the suggestion. Like for instance, clicking on a trace, a drop down menu for the min/max & their coordinates, the slope, roots, intersection, etc, etc ... [see Stuart list]. All those features can be programmed, but the idea is for immediate conviviality and analysis.
One of the defect that should be corrected is the "draw lines". It should draw a line between the start/end segment w/o attempting to interpolate and draw non existing segment, see the 2nd plot. Alternately, the points is good but on too few points it shows nothing or not enough.
Do you read Mona ?
