Or say, how can I prevent movement of HorizontalLineAnnotation when dragging the grip of X1(typically the left grip)?

Hello, I have added YAxisDragModifier and ZoomPanModifier to my surface and when I try to drag on Y axis I can move the X axis too and that is not the behavior that I was trying to get. I want when I drag/move YAxis not to move on the YAxis also.

Here is my code:

Surface.ChartModifiers.Add(new PinchZoomModifier());
Surface.ChartModifiers.Add(new ZoomExtentsModifier());
Surface.ChartModifiers.Add(new YAxisDragModifier { DragMode = AxisDragModifierBase.AxisDragMode.Pan });
Surface.ChartModifiers.Add(new XAxisDragModifier { DragMode = AxisDragModifierBase.AxisDragMode.Pan, ClipModeX = ClipMode.None });
Surface.ChartModifiers.Add(new ZoomPanModifier
{
Direction = Direction2D.XDirection,
ZoomExtentsY = false
});

Here is the video with the behavior:

Hi,

I have a VerticalLineAnnotation that can be dragged over the chart by clicking and dragging on the line itself. (See attached image). The problem is, whenever I put the chart in front of a user, they try to drag by clicking on the label (the blue label with the time in the image).

How can I make this label draggable like the line?

Thanks.

I have a set of ChartModifiers on my SciChartSurface, carefully configured to work together like so:

<s:SciChartSurface.ChartModifier>
    <s:ModifierGroup>
        <s:LegendModifier x:Name="LegendModifier" />
        <s:ZoomPanModifier ExecuteOn="MouseRightButton" ClipModeX="None" />
        <s:RubberBandXyZoomModifier ExecuteOn="MouseLeftButton" />
        <s:SeriesSelectionModifier />
        <s:ZoomExtentsModifier ExecuteOn="MouseDoubleClick" />
        <s:MouseWheelZoomModifier />
    </s:ModifierGroup>
</s:SciChartSurface.ChartModifier>

I also have a pair of VerticalLineAnnotations, which I create in the C#. These are used to select points on the series that has been selected with the SeriesSelectionModifier.

The problem is that after the sliders are dragged, the mouse up event causes the selected series to be unselected. How can I prevent this from happening?
