SciChart® the market leader in Fast WPF Charts, WPF 3D Charts, and iOS Chart & Android Chart Components

I was able to develop and run everything using the scichart alpha build from Jun 11th.
This includes SciChart2D, SciChart3D, with a minor error.
I was using .NET Core 3.0 Preview 6+, Visual Studio 16.3 Preview on a Win7 box.

However, the client wants to upgrade to Windows 10.
So I installed Visual Studio 16.3 (2019), and .NET Core 3.0 and I was able to build all the packages etc.

However, when launching the WPF part of the application, I was at first encountering AccessViolation exceptions in CreateRenderTarget().

I removed all my SharpDX components, and tried again. I was able to get around this problem by using a version of SciChart 6.0 greater than the Jun 11th alpha version – v. 6.0.0.12382-alpha.

I can now load SciChart2D package.

However, SciChart3D is now throwing null reference exceptions when loading. I’ve included the screenshot. This occurs even with the 6.0.0-beta version.

Please advise.

Hello everybody.
Library is really great, but rarely crashes and stack trace is not telling something useful to me.
May be somebody meet that exception and know the reasons?
Thanks.

The exception happens on the GC finalizer thread and has the following call stack:

SharpDX.dll!SharpDX.ComObject.SharpDX.IUnknown.Release() Line 256 C#
SharpDX.dll!SharpDX.ComObject.Dispose(bool disposing) Line 286 C#
SharpDX.dll!SharpDX.DisposeBase.CheckAndDispose(bool disposing =

I have a single SciChartSurface that is plotting a single FastImpulseRenderableSeries, which is bound using MVVM (SeriesBinding/ImpulseRenderableSeriesViewModel). Only debug builds appear to be affected.

Do I need to be disposing or otherwise cleaning up any of the SciChart objects I create?

Hi,

I’m evaluating SciChart for use in a production app.

Is there any way to log exceptions generated by SciChart? Currently I’m logging all handled and unhandled exceptions in my app to my server so that issues can be flagged without users having to manually submit support tickets. SciChart is printing internal exceptions to console – is there any way to override that with our own error handling mechanism? If not, how should we monitor for production errors generated internally by SciChart?

Thanks

I’ve installed the trial/demo SciChart and am trying to use it in my project to test performance.

The sample project works well and the WPF Examples Suite also works fine.

I’m referencing all the SciChart dlls in my project and added a simple bar chart that I copied from the Examples Suite. The app starts up well, but when the view that contains the bar chart is loaded, I get an exception saying: “The registry key specified by the RegistryStoragePath property could not be opened.” (See attached image Exception.png).
Trying to debug and find out what’s going on, the attached “Process Monitor.png” image is the result of the registry access from my App when loading it (I’m not sure if it helps, though).

Any thoughts on what can be happening?

Thanks,
Andre.

I’m trying to change the AutoRange property of my axis in a VisualStateManager storyboard and it’s throwing an exception saying the value is invalid. Is this not possible or should the object/property be accessed differently?

Exception: “The animation(s) applied to the ‘AutoRange’ property calculate a current value of ‘AutoRange.Once’, which is not a valid value for the property.”

<Storyboard>
<ObjectAnimationUsingKeyFrames Storyboard.TargetProperty="AutoRange" Storyboard.TargetName="XAxis">
<DiscreteObjectKeyFrame KeyTime="0" Value="AutoRange.Once"/>
</ObjectAnimationUsingKeyFrames>
</Storyboard>
.
.
.
<sc:NumericAxis x:Name="XAxis" AxisTitle="Time (s)" TitleFontSize="14" AutoRange="Always"/>

Thanks!
