I am showing tooltip with CursorModifier. My tooltip bigger than SciChartSurface and I am using ClipModifierSurface=”False” in order to show whole tooltip. But in this case axis labels and scroll bar are on top of tooltip.
Described problem can be seen on Featured Apps > Scientific Charts > Oscilloscope Demo.
Is there any way to bring tooltip on top of chart surface?
Thanks

Using custom label provider I am able to format the cursor label, but still there is the name of the axis. I only want to show the value here, like “0,91” and remove the “X:” (see attached screenshots).
Thanks in advance.
override func formatCursorLabel(_ dataValue: SCIGenericType) -> String! {
return "" // super.formatCursorLabel(dataValue)
}

Hi SciChart,
Our requirement is to have polygon shapes be drawn at runtime, and to have a “rich” tooltip display for the user when the user hovers over one of these polygons.
Using a CustomRenderableSeries, we’re able to plot polygons, each as its own CustomRenderableSeries. The tooltip displays on a mouse hover when the mouse is within a few pixels of the edge of polygon, but it does not display when the mouse hover is in the middle of a polygon.
We have also explored creating CustomAnnotations of these polygonal shapes – however, the CustomAnnotation object type does not have a ‘Path’ or ‘Points’ property as is shown in the arrow shapes declared in the XAML of the ‘Annotations are Easy’ WPF example. Because we won’t know the paths of these shapes until runtime, this does not meet our requirement.
Is there a way to have tooltips appear within polygons, or a way to assign ‘Path’ data to a CustomAnnotation? Or any other ChartModifier that might suit our needs?
Thanks!

Hi ,
I am facing a issue with the tooltips.When the scichart surface width is small or the window that has the scichartsurface is small the tooltips are not coming out of chart surface. I can reproduce the issue in Scichart sample(CustomTooltipsWithModifiers) also.
I even tried setting ClipModifierSurface =”False” ClipToBounds=”False”, but no luck. I still have the issue.
FYI , I am attaching the .png files. I cannot attach the sample project here because the allowed upload size is smaller.
Thanks,
Rakesh Bandari.

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 the Cross CursorModifier with axis labels and tool tips on a FastCandlestickRenderableSeries only. I have been using the CursorModifier:SnappingMode=”CrosshairToSeries” however I would like to only have the X axis of the CursorModifier snap to the nearest X data point of the series. This way the Y axis of the CursorModifier is still free to view price and hold a reference for where the Tooltip should be displayed. Any direction to the proper documentation for this functionality would be appreciated.
Thank you,
