I have a vertical slice modifier. Currently whenever a series has a point near the marker, a kind of tooltip is displayed showing th value of that series at that point. I want to turn off this tooltip functionality (not sure if its called AxisLabel, SeriesValue or something else).

Ive tried setting various properties but I’m still getting the tooltip. Can someone point me in the right direction :

               <s:VerticalSliceModifier  s:SeriesValueModifier.IsSeriesValueModifierEnabled="False" ShowAxisLabels="False" >
                                            X1="{Binding ...}"

Hi there
I have strange behavior with VerticalSliceModifier and ToolTipLabel.
Here we have line with x=88 and y=76.0
wring line Y value

Look at the data used as source for this series.
88 X value corresponds 11 index in the X values array, but there is other value under 11 index in the Y values array (77.3vs76):

X values
Y values

With using vs2015 Live Property Explorer you can see the current DataSeriesIndex = 10.

Actual current index

But if I zoom this chart the Y value becomes 77.3

After zoom value becomes OK

So what can I do with this problem?

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)

I’m having trouble making the RolloverModifier TooltipLabels stay inside the graphs canvas.


As you can see on the left most graph the colored sqaures and some of the digits has fallen outside the graphs canvas.
Also what are the TooltipLabels rules for clustering together, and rules for which side of the RolloverMarker the labels should appear on?

Still having a problem here… After setting the ClipModifierSurface on the SciChartSurface to False the time axis no longer clips the TooltipLabels.
But the graph itself clips the TooltipLabels when the label gets to large.

How do I make the labels stay inside the graph? As there is a lot of free space to the right of the labels.

Hi all,

I would like to ask how to modify the label of the OHLC Chart in Android.
For example, in the attached screenshot, how to change the label “Highest” to “High” ? Thanks.

I want to change to font name & font size for all modifier tooltips (CursrorModifier, RolloverModifier and so on )

I discovered that all tooltips use TextBlocks with style HintDataItemsStyle. This is its definition:

  <!--  Label used in cursors  -->
  <Style x:Key="HintDataItemsStyle" TargetType="TextBlock">
      <Setter Property="apc:RelativeSourceBinding.AncestorType" Value="r:TemplatableControl"/>
      <Setter Property="Foreground" Value="{Binding Path=(apc:RelativeSourceBinding.Ancestor).Foreground, RelativeSource={RelativeSource Self}}" />
      <Setter Property="FontWeight" Value="{Binding Path=(apc:RelativeSourceBinding.Ancestor).FontWeight, RelativeSource={RelativeSource Self}}" />
      <Setter Property="FontFamily" Value="{Binding Path=(apc:RelativeSourceBinding.Ancestor).FontFamily, RelativeSource={RelativeSource Self}}" />
      <Setter Property="FontSize" Value="{Binding Path=(apc:RelativeSourceBinding.Ancestor).FontSize, RelativeSource={RelativeSource Self}}" />
      <Setter Property="Margin" Value="{Binding Path=(apc:RelativeSourceBinding.Ancestor).Margin, RelativeSource={RelativeSource Self}}" />

So, I feel this would be easy to change font parameters just setting them to some parent (due to RelativeSourceBinding.Ancestor binding). But I cannot figure out which. I tried to change font size for series, for axes and even for surface – no result.
