I cannot get panning to work on the x axis which is a DateTimeAxis. I am databinding the visible range to a property on my view model and the zooming works ok. Also panning on the Y-axis works.

Here is my XAML:

<s:SciChartSurface x:Name="_sciChartSurface" Grid.Row="1" Grid.ColumnSpan="2" RenderableSeries="{s:SeriesBinding PlotViewModels}">
            <s:SciChartSurface.XAxis>
                <s:DateTimeAxis AxisTitle="{Binding HorizontalTitle}" VisibleRange="{Binding HorizontalRange, Mode=TwoWay}" AutoRange="Never"
                            IsStaticAxis="True" DrawMajorBands="False" TextFormatting="dd-MMM-yyyy" SubDayTextFormatting="H:mm:ss:tt"
                            AutoTicks="True"/>
            </s:SciChartSurface.XAxis>
            <s:SciChartSurface.YAxis>
                <s:NumericAxis AxisTitle="{Binding VerticalTitle}" AxisAlignment="Left"  VisibleRange="{Binding VerticalRange}"
                           AutoRange="{Binding AutoRange}" DrawMajorBands="False"/>
            </s:SciChartSurface.YAxis>

            <s:SciChartSurface.ChartModifier>
                <s:ModifierGroup>
                    <s:RubberBandXyZoomModifier IsXAxisOnly="False" 
                                            ZoomExtentsY="True" 
                                            IsAnimated="True" 
                                            RubberBandFill="#55FFFFFF" RubberBandStroke="#FFFFFFFF" RubberBandStrokeDashArray="2 2">
                    </s:RubberBandXyZoomModifier>

                    <s:ZoomPanModifier ExecuteOn="MouseRightButton" ClipModeX="None" XyDirection="XYDirection" IsEnabled="True" />
                    <!-- Allow Dragging YAxis to Scale -->
                    <s:YAxisDragModifier DragMode="Scale"/>
                    <!-- Allow Dragging XAxis to Pan -->
                    <s:XAxisDragModifier DragMode="Scale" IsEnabled="True"/>

                    <s:MouseWheelZoomModifier ActionType="Zoom" XyDirection="XYDirection"/>

                    <s:ZoomExtentsModifier IsAnimated="True" ExecuteOn="MouseDoubleClick"/>
                </s:ModifierGroup>
            </s:SciChartSurface.ChartModifier>
        </s:SciChartSurface>

Hi,

I’m trying to limit the x-axis panning up to an annotation that I’ve drawn on the graph. This annotation can be beyond the current data’s position (i.e. data’s timestamp is at 5/4/2017 11:00:00, annotation’s position is at 5/4/2017 16:00:00). Is there a method, or any way that I can use to limit the x-axis panning up to the annotation’s position instead of limiting it to the data series’ max X?

Regards.

How do I implement mouse wheel zooming so that the point under the mouse pointer (before zoom), will also be under the mouse pointer after the zoom?
The chart is a 2D chart with DateTime X axis and multiple value Y axes.

Hi Scichart,

I am struggling with a ContextMenu on a SciChartSurface that wont be displayed.

The problem started when i added mouse panning with the right mouse-button which is the same button the ContextMenu is activated on.

So will this combination even work – with both a ContextMenu and mouse panning with the right mouse button?

To manually validate if the ContextMenu should open or if the panning should be enabled, I have tried to get the mouse coordinates manually in C# to see if the mouse was moved(panning) or if it was a click(ContextMenu). This did not work very well when i afterwards started to pan/zoom again.

Do you have a code example using both a ContextMenu and mouse panning using right mouse button?

Best regards,
Jeppe
