Hi scicharts team,
For our application we have a point and series selection feature for a Line Chart but i have noticed that When i select a point and highlight it, Series selection changed function also gets triggered even though i didnt want to select the series.
Is there any work around for this that can suppress the sereis selection when clicking data point ?

Hi Rahul,
This is by design, whenever you hit a “dataPoint” via DataPointSelectionModifier(), you still hit a series, so that gets triggered.
But, when you hit a series, SeriesSelectionModifier() does not always hit an exact data-point (where the point-marker sits) cause it can hit in between points and still return a hit for the series.
One easy fix is to loop over all renderable series that are NOT supposed to have both a series & data point selection modifier and run this on them:
const ssm = new SeriesSelectionModifier({
onSelectionChanged: (args) => console.log("SERIES CHANGED")
});
// for this purpose, this next line removes the series selection modifier on all series, but you should only do this on series that need just a DataPointSelectionModifier.
sciChartSurface.renderableSeries.asArray().forEach(rs => ssm.includeSeries(lineSeries, false));
Hope this helps!
Best,

Hi Andrei,
i dont think this exactly solves my issue,
All my renderable series need to have both SeriesSelectionModifier and DataPointSelectionModifer, but onChange of datapoint i need to suppress the Series’s onchanged function since im only clicking on a point marker

Hi Rahul, noted, and I passed the same feedback to our team – that users may wish to have both DataPoint selection and SeriesSelection enabled. Working on it
