When we move the cursor fast in Sci Chart surface, Sometimes its making customized tooltip (cursor Modifier) to freeze. We are not having this issue in landscape mode. we have this issue only when we use it in half of fragment.
View hierarchy:
swipe refresh>
nested Scrollview>
constraint layout>
view> –50% of screen
Sci Graphview> –50% of screen
/ constraint layout>
/nested Scrollview>
/swipe refresh>

We have a sciChart surface in a fragment that has a scrollable view. We enabled tooltips using custom cursor modifier on the sci chart to show the values as the selection (touching a point in the chart object).
When we are moving the selection on x-axis tooltip sometimes it works fine and disappears when the selection is taken out. But sometimes it get freezed. At the same time, if we touch and move the selection in a vertical axis, tooltip box gets stuck and does not disappear even when the selection is taken out.
Tried so far:
We tried to replicate the issue in landscape mode and it works fine.
If we make the chart object to the whole page view, tool tips appears and disappears as expected.
But when the same used in portrait mode as a part of fragment (50% of screen) , problem arises
Steps to reproduce:
Have a chart object in a scrollable view.
Make sure the chart object doesnot appear on the fully screen without scrolling.
Now scroll to see the chart object.
Try to see the tooltip and move the selection in vertical axis.

Hello, I am using SciChartJS and have a new requirement from our users as follows that I need help with the implementation. Any pointers from anyone would be a great help.
**Requirements: **
- Assume that x-axis is Time and y-axis is prices.
- There are multiple series in the chart (e.g., Bid Price, Ask Price)
- Allow user to select a time on xAxis using
CTRL + CLICK - When the user selects the time, show the rollover line and the tooltip for all series at the selected time
- This rollover line and tooltip should remain visible until the user selects a new time on the x-axis at which point the rollover tooltip should display the tooltip for the new point.
I started inheriting the RolloverModifier but couldn’t find an appropriate method to show the tooltip.
So, I started implementing the above feature using CustomModifierBase2d and adding a VerticalLineAnnotation for the rollover line. But again, struggling with the tooltip.
If someone could help me out or give me pointers, that would be highly appreciated.
Best Regards,
Sachin Patel.

As if right now, I have create a custom annotation, which is a red circle and the idea is to show some info when hovering on it, like a tooltip.
Right now, when hovering on the red circle, I am adding another custom annotation to show the info and then removing it when not hovering anymore. The issue with this is that it is not very stable, as in if I don’t point my cursor right in the middle of the red circle, it won’t register as hit. I tried putting hitTestRadius to 50 on CursorModifier, but doesn’t seem to make any difference.
I have also try with xyScatterRenderableSeries and EllipsePointMarker, the issue I find with it is that it is interfering with my data series tooltip, as the cursor modifier recognize it as a chart series and try to show on the tooltip, which I don’t want. I only want the red circle to be trigger only when cursor is right on it.
The first image is my code and how I am trying to achieve it at the moment, it does work, but I don’t think it’s very stable, I wish there is a more natural way to do it.
The second image is how my current solution looks like, as you can see, the data series tooltip is overlapping it, which I want to avoid. I can’t think of a way to solve the overlapping issue yet. Other than unstableness and the tooltip overlapping, it work fine.
The third image is how I want it to look like.

Hello, how do I remove the shadow from tooltips, generated by the VerticalSliceModifier?
Thanks!

The chart is only showing 3 of 4 Tooltips, is there a way to avoid this?
