Secondary Y-Axis for Chart (No scroll bar)

[Houssem]

Hi

I have added Secondary Y-Axis for Chart but the scroll bar on the both Y-Axis is not shown anymore.

Is there any fix for this issue?

Thanks

Hello Sam,

Can you clarify which chart you are using RadChart or RadCartesianChart?

Note that the RadCartesianChart is displaying the panzoombar  (the scrollbar) only for the main axes (the ones set on the Vertical/HorizontalAxis property of the chart). If you don't have a main axis set the panzoombar won't be displayed.

Also, there is a feature request for multiple axes with separate panzoombars logged in our feedback portal. You can also check the IndividualAxisZooming SDK example.

Ok then while setting the vertical axis in Telerik.Windows.Controls.ChartView.CartesianSeries, the panzoombar  (the scrollbar) is not shown at all. It there a way to display it? 

Thanks

Hello Sam,

Yes, you can display the zoombar if you set also the VerticalAxis of the RadCartesianChart. If you don't want to see the chart's vertical axis you can set its ElementBrush property to Transparent. Here is an example in code:

<telerik:RadCartesianChart>
    <telerik:RadCartesianChart.VerticalAxis>
        <telerik:LinearAxis ElementBrush="Transparent" />
    </telerik:RadCartesianChart.VerticalAxis>
    <telerik:RadCartesianChart.HorizontalAxis>
        <telerik:CategoricalAxis/>
    </telerik:RadCartesianChart.HorizontalAxis>
    <telerik:RadCartesianChart.Behaviors>
        <telerik:ChartPanAndZoomBehavior ZoomMode="Both" />
    </telerik:RadCartesianChart.Behaviors>
    <telerik:AreaSeries>
        <telerik:AreaSeries.VerticalAxis>
            <telerik:LinearAxis />
        </telerik:AreaSeries.VerticalAxis>
        <telerik:AreaSeries.DataPoints>
            <telerik:CategoricalDataPoint Value="20"/>
            <telerik:CategoricalDataPoint Value="40"/>
            <telerik:CategoricalDataPoint Value="35"/>
            <telerik:CategoricalDataPoint Value="40"/>
            <telerik:CategoricalDataPoint Value="30"/>
            <telerik:CategoricalDataPoint Value="50"/>
        </telerik:AreaSeries.DataPoints>
    </telerik:AreaSeries>
</telerik:RadCartesianChart>
