I have problems with RolloverModifier while dataseries are UnsortedXyDataSeries. If I change to (sorted)XyDataSeries everything OK. I didn’t find any information in documentation that this modifier has such restriction.
Second question about sorted series: does Append(x,y) of XyDataSeries require to be last point of x range or it can append to any place of existing range?
Update June 2014
SciChart 3.0 has been released and UnsortedXyDataSeries is now obsolete. Now you can append sorted or unsorted data to XyDataSeries, the chart will automatically determine the data distribution (Sorted, Unsorted, Evenly Spaced, Unevely Spaced)
3. UnsortedXyDataSeries is now Obsolete
However, note that vastly superior performance can be achieved when data is Sorted in the X-Direction. For more information, please see our Performance Tips and Tricks article.
The hit-test functionality(which RolloverModifier relies upon) was implemented for the UnsortedXyDataSeries in SciChart v3.0. Please, check if you use the proper version.
Regarding the second question, the Append method adds a data point to the end of the DataSeries. If you need to insert points, please, try using the Insert/Remove methods. Is it applicable in your case?
