Prior to our recent upgrade to 2016.1.113.40 the below chart rendered fine, after our upgrade, we get a JS error. To correct this I had to change the series from LineSeries to a ScatterLineSeries.

Is this a known issue?

JS error with above.

Changing the Series to a ScatterLineSeries versus LineSeries seems to have resolved this. I also changed the DataFormatString on the Label to 1.

<Series>

<telerik:ScatterLineSeries DataFieldX="Day" DataFieldY="RunningGoalAmount" Name="Monthly Goal">

<Appearance>

<FillStyle BackgroundColor="Blue" />

</Appearance>

<LineAppearance LineStyle="Smooth" Width="3"/>

<LabelsAppearance Visible="false"></LabelsAppearance>

<MarkersAppearance MarkersType="Circle" Size="8" />

<TooltipsAppearance Color="White" DataFormatString="{1:C0}"></TooltipsAppearance>

</telerik:ScatterLineSeries>

</Series>

<Series>

<telerik:ScatterLineSeries DataFieldX="Day" DataFieldY="RunningTotalAmount" Name="Shipments">

<LineAppearance LineStyle="Smooth" Width="3" />

Hello,

Please ignore my previous post. This is actually an issue with the control - when the MinValue property is defined for an empty or data-bound x-axis with line/area series, a JavaScript error is thrown. The issue has been logged here (http://feedback.telerik.com/Project/108/Feedback/Details/181171), so that you can monitor, comment and vote on it.

I have also updated your Telerik points for helping us improve the quality of our Telerik UI for ASP.NET AJAX suite.
