I use MouseWheelZoomModifier. If some modifier key pressed (Ctrl, Shift, Alt) it produces scroll instead of zoom. My X axis is styled as follows:

<Style TargetType="s:DateTimeAxis">
            <Setter Property="TextFormatting" Value="dd-MM-yyyy"/>
            <Setter Property="SubDayTextFormatting" Value="HH:mm:ss"/>
            <Setter Property="AutoRange" Value="Never"/>
            <Setter Property="GrowBy" Value="0.1, 0.1"/>
            <Setter Property="AxisAlignment" Value="Bottom"/>
            <Setter Property="VisibleRangeLimitMode" Value="MinMax"/>
            <Setter Property="VisibleRange" Value="{Binding Mode=OneWay, RelativeSource={RelativeSource Mode=Self}, Path=VisibleRangeLimit}"/>

VisibleRangeLimit is set in code behind. So as you can see X axis can not go out of VisibleRangeLimit. So we came to my problem: with MouseWheelZoomModifier if I hold Ctrl button and scrolling, when X axis comes to limit it starts to zoom X axis.
The same happens with ZoomPanModifier, but in ZoomPanModifier it can be disabled by setting ClipModeX=”ClipAtExtents”, so when you approaches to the border and continue panning it simply do nothing – that’s what behavour I need in MouseWheelZoomModifier with Ctlr key pressed. I could not find anything like this in MouseWheelZoomModifier. Any ideas?

I want the chart to scroll from right to left and stop at left side. Don’t automatically scale, don’t move right.

I have a modifier:

ZoomPanModifier zoomModifier = new ZoomPanModifier() { ... };
// zoomModifier.setClipModeX(ClipMode.ClipAtMin);

When I scroll a chart left to the beginning, it scales the chart to one screen. So, all points are visible, proportions are broken.
When I replace “ClipMode.ClipAtExtents” to “ClipMode.ClipAtMin”, it sometimes stops at left side (as desired), but if I swipe too fast, it shows a right part of the chart and continues to scroll left.
Currently a first version of the SciChart library is installed.
As written in both “ClipAtExtents” and “ClipAtMin” have another behaviour.
My question is similar to, but for Android.

Answer, please, is it a bug? Has it been already fixed or expected to be fixed?

I have ClipModeX=”ClipAtExtents” on my ZoomPanModifier. I need the same behavior on the y-axis, but there is no “ClipModeY”.

How do I prevent y-axis data from panning off the chart?
