Hello,
I am having a problem where I want to display the Rollover Modifier only when I click on the selected graph.
For example:
https://demo.scichart.com/javascript-chart-rollovermodifier-tooltips
If I select the Second Lines Series, I want to see the rollover only for that particular graph and not the first one and the third one.
I have tried using charts id’s as a reference to show only one tooltip but it just enables it for all the graphs.
Any help would be kindly appreciated.

Hello,
To implement this you would probably need the Series Selection API in combination with a custom Rollover Modifier.
class CustomRolloverModifier extends RolloverModifier {
getIncludedRenderableSeries() {
return super.getIncludedRenderableSeries().filter((rs) => rs.isSelected);
}
}
const rolloverModifier = new CustomRolloverModifier({
showRolloverLine: true,
showTooltip: true,
// ...
});
const seriesSelectionModifier = new SeriesSelectionModifier({
enableSelection: true,
onSelectionChanged: (args: SelectionChangedArgs) => {
args.allSeries.forEach((rs) => {
rolloverModifier.includeSeries(rs, false);
});
rolloverModifier.includeSeries(args.selectedSeries[0], true);
},
});
sciChartSurface.chartModifiers.add(rolloverModifier, seriesSelectionModifier);
Here is a live CodeSandbox Example:
