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

I was curious, and had mentioned this in another thread, but verified what I thought. My first SciChart instance is drawing in DirectX and subsequent charts are not. Please see attached. Each chart is being created and placed inside a tabitem.

I used the suggested annotation to show the version being used (from the support forum) and found why my images are not as crisp in most of my charts.

In the designer I’m seeing this. It doesn’t seem to affect the application; however, I can’t see any of my XAML in the designer because of this problem. Also, I’m having a strange intermittent issue with multiple instances of the chart in my UI not being as smooth and sharp after adding a few charts.

I just purchased a license for WPF 2D+3D (Pro) and tried to use a scichartsurface without DirectX and it works fine but as soon as I include

                s3D:DirectXHelper.FallbackType="{x:Type s:HighSpeedRenderSurface}"

I get the following runtime error:

System.Windows.Markup.XamlParseException: ‘Could not load file or assembly ‘SciChart.Drawing.DirectX, PublicKeyToken=b55dd9efe817e823′ or one of its dependencies. The system cannot find the file specified.’

What am I doing wrong? I installed the newest Scichart version on the Nuget channel. In Nuget I can see that “SciChart”, “SciChart3D”, “SciChart.DirectX” and a bunch of SharpDX libraries were installed.

I use your library. and I want to use directX.

but when I open a page using this(following your article),

I saw a error message and my program was terminated…

but I imported that in my project.

and Debug or Release folder has that dll.

This problem occured on another computer…(installed directX driver/ OS is Win7)

My development PC is fine.(Win10)

Why is it??

Please tell me awesome solution…

I developed a program using scichart.

Unfortunatly, It can not work on some computers.

There are same hardware and OS(Window 7).

I found this problem when I use DirectX.

I have referenced your code. and My code had ChangeRenderSurface method.

but It can not work well…

I think the problem occurred when I called scichart3d.

What is wrong?

Does it need to install anything else?

If you have a solution , please tell me.

I use a scatter series that contains around 200,000 data points and I noticed that in the DirectX assisted rendering mode (not sure it also applies to the normal non DirectX mode) scatter points are sampled, meaning, not all scatter points are visible on the chart surface.

How can I turn that off to display all data points even if that may affect performance? I chart financial time series and the chart often shows discrete jumps when there are actually many data points in between when zooming in.

I have just finished my first pass evaluation of the SciChart performance. When drawing a lesser number of points (<100000), SciChart outperforms two other packages I have evaluated. However, when drawing more points (200,000 – 2,000,000), SciChart does not meet the performance of the other packages.

The evaluation involved selecting a different number of lines and number of points per line. The transition to worse performance occurred in the following setups:

Line Count Points/Line Loop Count Total Time (ms)
2 100,000 25 1890
5 100,000 25 4670
2 1,000,000 10 7400
2 10,000,000 10 74000

These setups average out to about 0.37 usec per point. This is where the other packages outperformed SciChart, as their per point times kept improving.

I have tried to follow all of the performance tips I found on your website. I have included the code used to evaluate SciChart and would appreciate any help in improving the results.
