Tag: MouseWheelZoomModifier

Hi.

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}"/>
        </Style>

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 need MouseWheelZoomModifier to work only when I pressed mouse button. I wrote:
<s:MouseWheelZoomModifier ExecuteOn="MouseRightButton" />
But it all the same executing when I’m not pressing mouse button. Why?

Dear all,

Does anyone of you have a solution in order to avoid zooming out too much when using the mouse wheel button ?
What I means is that if you call the ZoomExtents the graph will zoom out to fit in chart viewport. By using the mouse wheel is there a way to stop zooming where we reach zoomextents range ?

Hi,

in a MVVM scenario, I bind the AnimatedVisibleRange to a property in the view model.

 <s:SciChartSurface SeriesSource="{Binding ChartSeries}">
   <s:SciChartSurface.XAxis>
     <s:NumericAxis AxisTitle="x" AnimatedVisibleRange="{Binding XVisibleRange, Mode=TwoWay}" AutoRange="Never" />
   </s:SciChartSurface.XAxis>
   <s:SciChartSurface.YAxis>
     <s:NumericAxis AxisTitle="y" AnimatedVisibleRange="{Binding YVisibleRange, Mode=TwoWay}" AutoRange="Never" />
   </s:SciChartSurface.YAxis>
   <s:SciChartSurface.ChartModifier>
     <s:ModifierGroup>
       <s:MouseWheelZoomModifier IsEnabled="True" XyDirection="XDirection"/>
     </s:ModifierGroup>
   </s:SciChartSurface.ChartModifier>
 </s:SciChartSurface>

Setting the XVisibleRange property in the view model smoothly animates the view. However, when I zoom in the chart with the mouse wheel, the view model property receives no updates (so the XVisibleRange property in the view model always stays on the value initially set by the view model).

The same thing works when I bind he VisibleRange instead of the AnimatedVisibleRange, i.e. in that case I get an update of the view model property on every mouse wheel zoom.

Is this intendend, or a bug? Building a workaround would require additional bindings, which I would like to avoid.

Best regards,

Andree

Hi~ supporter

On testing scichart for a migration of our chart library, I had a some problems.

Because I tested scichart for just two days so It maybe my mistakes..^^

1. MouseWheelZoomModifier does not work.

– If There is no series on chart area, MouseWheellZoom works well but After add curve, It stop working.

1. Rubber Band Zoom for Stacked bar chart

– After adding serveral stacked bar charts, When I try to do rubber band zoom for stacked bar chart, Stacked bar often disappear.

1. ZoomExtants for Stacked bar chart

– After adding several stacked bar charts, When I call “ZoomExtants()”, all stacked bar charts does not fit in chart area.

I attached a sample program.
I will looking forward to your answer.
