Hello,
i’m trying to build a chart using a Stripe Data series, on the X axis i have a DatetimeAxis while on Y axis i have a Numeric.
I have an observable collection of IRenderableSeriesViewModel, and when i try to add a StripeRenderableSeriesViewModel if the dataseries contains many elements (>2000) it logs this exception below:
Exception thrown: ‘System.InvalidCastException’ in System.Private.CoreLib.dll
SciChartSurface didn’t render, because an exception was thrown:
Message: Invalid cast from ‘Double’ to ‘DateTime’.

at irv.hds(jbq r, SCRTRenderContext s)
at jbv.Dispose()
at SciChart.Charting.Visuals.SciChartSurface.DoDrawingLoop()
Binding and data i’m pretty sure are ok since with fewer data it works fine
EDIT: i was able to reproduce the issue in the wpf sample project (repo), just replace GanttChartViewModel.cs with the sample one i have attached here and it can be reproduced by navigating to the Gantt chart example

My application intermittently output the following exception log:
System.InvalidOperationException: Enumerator version is invalid
Location: hbq`1.ghm.uqc()
InvalidOperationException could be thrown when a collection is modified while iterating of IEnumerable collection
However, it usually outputs the following exception message:
“Collection was modified; enumeration operation may not execute.”
(NOT is “Enumerator version is invalid”)
When and under what conditions can this exceptions occur?
When an exception occurs, the call stack is as follows:

After update to SciChart.6.2.1.13304 we get an InvalidOperationException:
This SciChartSurface instance is disposed, you cannot set a RenderSurface on it at this time

I have no idea what happen. This is how we initalize SciChart:
<s:SciChartSurface x:Name="sciChart"
Grid.Column="2"
RenderPriority ="Low"
s:PerformanceHelper.EnableExtremeDrawingManager="True"
s:PerformanceHelper.EnableExtremeResamplers="True"
s:VisualXcceleratorEngine.DowngradeWithoutException="True"
s:VisualXcceleratorEngine.FallbackType="{x:Type s:HighQualityRenderSurface}"
s:VisualXcceleratorEngine.AvoidBlacklistedGpu="False"
s:VisualXcceleratorEngine.EnableImpossibleMode="True"
s:VisualXcceleratorEngine.IsEnabled="{Binding Path=DirectXSupport, FallbackValue=True}"
s:SciChartGroup.VerticalChartGroup="{Binding Path=ChartViewModel.VerticalChartGroupKey}"
Style="{StaticResource SciChartSurfaceStyle}"
GridLinesPanelStyle="{StaticResource DefaultGridLinesPanelStyle}"
RenderableSeries="{s:SeriesBinding RenderableSeriesViewModels, UpdateSourceTrigger=PropertyChanged}">
Any idea?

Right now I’m encountering a strange problem.
- Open C# WPF app containing SciChart on Windows Server 2012 R2 computer.
- Open a tabbed view that contains SciChartSurface.
- Press Ctrl-Alt-Del and Switch User. Select user and type in login password.
Instead of switching user, Remote Desktop can be used to log in to the Windows Server 2012 R2 computer. - After password is entered, an InvalidOperationException would occasionally appear. Enclosed is a popup dialog that appears when the exception occurs.
The error message says “Specified element is already the logical child of another element. Disconnect it first.”
However, the problem doesn’t occur every time though.
This problem never occurs on Windows 7, and it may be related to how DataContext gets changed in newer versions of Windows (like Windows 10 and Windows Server 2012 R2) after remote login or user switch.
Here’s a link to a StackOverflow question posted by someone else regarding this DataContext issue: http://stackoverflow.com/questions/40996366/wpf-view-constructor-called-on-windows-switch-user-or-remote-desktop-login
Somehow, a DataContext change would occasionally glitch up SciChart to produce this exception. This is problematic because one of our customers installed our WPF software application (containing SciChart) on a Windows Server 2012 R2 machine, and would remote login to that machine to run the app. Occasionally the Windows Remote Desktop would lose its connection (understandable), but when the customer logs in again, if the screen the customer was on contained a SciChart surface, the app would occasionally display the InvalidOperationException and crash.

Hi!
I’m having an issue with ZoomExtentsY, where it throws the exception InvalidOperationException.
My software reads sensordata from a stream and appends this data to the SciChart XyDataSeries<DateTime, double>.
I’m plotting a moving window of the data +/- 5 seconds which moves at 1 x speed of time forward. I use ZoomExtentsY to make the moving window show all the available data in that +/- 5 second segment in the Y-direction.
As I haven’t found any pattern on when/why the exception happens, it occurs rather random. Sometimes I can playback fine, but other times the exception happens within seconds of opening the SciChart-plot.
The exception message was: ‘Enumerator version is invalid’
Here is the StackTrace:

Good day, everybody!
Recently I’ve upgraded my project to new SciChart version (v3.1.0.4761 (13th July 2014)). Previos version is 3.0.2.4282 (1st May 2014).
I noticed that the project had a lot of freezes. I watched output data and found out this:
A first chance exception of type 'System.InvalidOperationException' occurred in Abt.Controls.SciChart.Wpf.dll
A first chance exception of type 'System.InvalidOperationException' occurred in Abt.Controls.SciChart.Wpf.dll
SciChartSurface didn't render, because an exception was thrown:
Message: AxisCollection.GetAxisById('DefaultAxisId') returned more than one axis with the ID=DefaultAxisId. Please check you have assigned correct axis Ids when you have multiple axes in SciChart
