Force labels to ticks with certain values?

[Clas Ericson]

Hi,
I'm wondering if there's way to force the labels of an axis to ticks with certain values, for example force the labels to tick 1.0, 1.5, 2.0, 2.5 and so on?

The chart where I want to use this has an linearaxis with pan and zoom enabled and if you zoom in and pan the labels can be positioned like 4.2, 4.7, 5.2, 5.7 and so on. If you pan a bit more they could be positioned as I want them to. It seems like it depends on the first visible value of the axis how the labels layed out.

Below is the XAML for my chart.

<telerik:RadCartesianChart
    x:Name="chart"
    Grid.Row="2"
    Grid.ColumnSpan="2"
    HorizontalAlignment="Stretch"
    VerticalAlignment="Stretch"
    Margin="0,0,0,0">
    <telerik:RadCartesianChart.HorizontalAxis>
        <telerik:LinearAxis
            LastLabelVisibility="Visible"
            Title="{Binding XAxisTitle}"
            LabelTemplate="{StaticResource labelTemplate}"
            LabelFormat="#.#"
            MajorStep="5"
            LabelInterval="5" />
    </telerik:RadCartesianChart.HorizontalAxis>
    <telerik:RadCartesianChart.VerticalAxis>
        <telerik:LinearAxis LabelFormat="P1" Title="{Binding YAxisTitle}" />
    </telerik:RadCartesianChart.VerticalAxis>
    <telerik:RadCartesianChart.Behaviors>
        <telerik:ChartPanAndZoomBehavior PanMode="Both" ZoomMode="Both" />
    </telerik:RadCartesianChart.Behaviors>
    <telerik:RadCartesianChart.Grid>
        <telerik:CartesianChartGrid MajorLinesVisibility="Y"  />
    </telerik:RadCartesianChart.Grid>
    <chartView:ScatterPointSeries AllowSelect="False" ItemsSource="{Binding EmptySerie}"  XValueBinding="XValue" YValueBinding="YValue" />
</telerik:RadCartesianChart>

Hello Clas,

Unfortunately the ChartView does not currently expose such settings. I am not familiar with your scenario, but what I can suggest for you to try is to use a VisibiliryConverter - to hide all labels except the ones that contain 1.0, 1.5 and so on. You will need to adjust, or even remove, the MajorStep and LabelInterval settings.

I have attached a project based on your code, in which I have added this converter. Let us know if it fits your scenario.

Kind regards,
