YAxisName property on CustomLine

[Brian]

I have a graph with 2 Y axis'.  I am adding custom lines relative to the second Y axis but the line is always relative to the first Y axis.  I am setting the name of my second Y axis and in the custom line I am setting the YAxisName property to the second Y axis.  I am assuming this would make the line relative to the 2nd Y axis but that is not the case. 

What am I doing wrong?
Tks.

Hello Brian,

Have you seen our help topic as well as our demo where it is shown how to create RadChart with multiple y axes? Also by saying "custom line" I hope you mean Line Series and not an annotation line, right?

I am not having issues creating multiple Y axis'.  When I say custom line, I mean a CustomLine, as in, Telerik.Windows.Controls.Charting.CustomLine.

Hello Brian,

I'm not sure what you mean by "in the custom line I am setting the YAxisName property to the second Y axis". In order to define the custom line you have to set the Slope and/or the YIntercept properties and the Line will be drawn according to the function y = mx + b, where 'm' is the Slope and 'b' is YIntercept. You may find more information on creating Custom Line in this help topic.

That help topic doesn't even mention the 'YAxisName' property of a CustomLine control.  I want my custom line drawn in relation to a second Y axis. 
I have 2 Y axis on my graph.  One on the left, one on the right.  I want the CustomLine drawn in relation to the Y axis on the right.  I assumed I could do this by setting the 'YAxisName' property but it is not working.  Should it?

Hello Brian,

This works fine for me. Please, find below my test xaml. Note, that the secondary AxisY in question should have its AxisName property set:

<telerik:RadChart x:Name="RadChart1">
<telerik:RadChart.DefaultView>
    <telerik:ChartDefaultView>
        <telerik:ChartDefaultView.ChartArea>
            <telerik:ChartArea>
                <telerik:ChartArea.AdditionalYAxes>
                    <telerik:AxisY AxisName="Secondary" />
                </telerik:ChartArea.AdditionalYAxes>

                                YIntercept="2"
                                Stroke="Red"
                                StrokeThickness="3" />
                </telerik:ChartArea.Annotations>
            </telerik:ChartArea>
        </telerik:ChartDefaultView.ChartArea>
    </telerik:ChartDefaultView>
</telerik:RadChart.DefaultView>
</telerik:RadChart>
