Hi all,
I have a chart : RadCarteisaonChart defined like this :
Is possible to change the Axis (X and Y) by Logarithmics Axis at runtime ?
Regards
<telerik:RadCartesianChart Grid.Column="0" Margin="0,30,0,30" Foreground="{StaticResource DarkGray}">
<telerik:RadCartesianChart.HorizontalAxis>
<telerik:LinearAxis x:Name="hLinearAxis" ShowLabels="True">
</telerik:LinearAxis>
<!--<telerik:LogarithmicAxis x:Name="hLogarithmAxis" ShowLabels="True">
</telerik:LogarithmicAxis>-->
</telerik:RadCartesianChart.HorizontalAxis>
<telerik:RadCartesianChart.VerticalAxis>
<telerik:LinearAxis x:Name="vAxis"/>
</telerik:RadCartesianChart.VerticalAxis>
<telerik:ScatterPointSeries x:Name="ChartCurve" XValueBinding="Concentration" YValueBinding="OpticalDensity" Foreground="{StaticResource DarkGray}">
<telerik:ScatterPointSeries.PointTemplate>
<DataTemplate>
<Ellipse Width="10"
Height="10"
Fill="{StaticResource ElectricBlue}"/>
</DataTemplate>
</telerik:ScatterPointSeries.PointTemplate>
</telerik:ScatterPointSeries>
<telerik:RadCartesianChart.Grid>
<telerik:CartesianChartGrid MajorLinesVisibility="XY" />
</telerik:RadCartesianChart.Grid>
<telerik:RadCartesianChart.Annotations>
<telerik:CartesianCustomLineAnnotation Stroke="Red" StrokeThickness="2" HorizontalFrom="0" HorizontalTo="{Binding CONCMAX}" VerticalFrom="{Binding A}" VerticalTo="{Binding YMAX}" />

Hello Didier,
You can achieve this by setting the VerticalAxis and HorizontalAxis properties of the chart in code behind. The following example code snippet changes the axes on a button click:
private void RadButton_Click(object sender, RoutedEventArgs e)
{
if (this.chart.VerticalAxis is LinearAxis && this.chart.HorizontalAxis is LinearAxis)
{
this.chart.VerticalAxis = new LogarithmicAxis() { LogarithmBase = 2 };
this.chart.HorizontalAxis = new LogarithmicAxis() { LogarithmBase = 2, ShowLabels = true };
}
else
{
this.chart.VerticalAxis = new LinearAxis();
this.chart.HorizontalAxis = new LinearAxis() { ShowLabels = true };
}
}That said, I have prepared a sample project implementing the following approach.
