I’m new to SciCharts, so this might be a terminology issue or something like that.
I’m trying to add a vertical line annotation to my chart that the user can drag around. So far so good. However, I’d like it to also display the values of the series data the line intersects with. This is where I’m unsure of the best way to proceed. What I want is basically the behavior of the RolloverModifier, which displays tooltips when it intersects with series data, but it’s always visible rather than triggered by a rollover. It may be possible to use the RolloverModifier for this, but I ran into an issue where I couldn’t have both a VerticalLineAnnotation with IsEditable=true and a RolloverModifier, and I need to add another VerticalLineAnnotation in addition to this one.
Hopefully I just missed something in the documentation.
SciChart v3.0 now supports a VerticalSliceModifier, which provides a draggable Vertical line which shows series values as Rollover style tooltips as you drag the line. You can see an example of it in action here:
Unfortunately, VerticalLineAnnotation doesn’t provide such a feature for now. However, some users have implemented this behavior by themselves, please, take a look at this thread and find the links in the last post.
Hope this helps!
