Getting Started...

Oct 11, 2011 at 12:35 AM

I feel a bit dense posting this, but I can't make heads nor tails of what I'm doing wrong.

<Window x:Class="DataMonitor.MainWindow"
        Title="Data Monitor" WindowState="Normal" Height="350" Width="525">
        <d3:ChartPlotter Name="plotter"></d3:ChartPlotter>

The above is the entire extent of my WPF window. I'm stuck here because I get the error, "The type 'd3:ChartPlotter' was not found. Verify that you are not missing an assembly reference and that all referenced assemblies have been built."

I have downloaded D3, placed the DynamicDataDisplay in my solution folder, and added the DynamicDataDisplay.dll as a reference in the project. I've been using as a guide.

I must be doing something that's really obviously wrong, but I can't figure it out. Any help? Did I miss a step in setting the project up?

Did you type in


 or browse for the assembly by typing


and then selecting from the intellisense list?


After doing that, if you type


does an intellisense list of components popup?


Is ChartPlotter in the list?

Copy/pasted it. And it doesn't appear in the IntelliSense list, so I guess that's where my problem lies. Are there any other references I need to add? Or what?

Your quick response is extremely appreciated. Thank you.

Do the D3 samples compile/run?


Do they have 


in their xaml?

Unfortunately, the samples I have are only the .dll's and the .exe's - no code.

I recommend you change to using the latest source code from

I've used that version for a long time without significant issues.

The main problem with either version is that development has stopped (but it's still the best wpf graph library for large data sets).

Oh my, I thought I had the most recent version.

The samples in the most recent version don't work, either. For example, the Coastline Sample has the warnings:

  1. The referenced component 'DynamicDataDisplay.Coastline' could not be found.
  2. The referenced component 'DynamicDataDisplay' could not be found.

So it's not finding ChartPlotter, either. When I look under the "references" folder in the project (in the solution explorer), and view the properties of DynamicDataDisplay and DynamicDataDisplay.Coastline, the "path" field is empty. I also tried typing "xmlns:d=" to see what popped up, and the doesn't show up (that specific line does already exist in the xaml).

Excuse me for perhaps being a bit dense, but do I need to make/generate the .dll files? Since I notice there's no .dll files in the stable version.

Wait... I got samples working. And found the .dll in the stable release.

I tried referencing the same .dll the samples were in my project, but I still don't get anything.

I'm so completely confused and frustrated. I feel like this ought to be simple, but I can't get it working.

Well. I got it working well enough. At least for the moment.

I added the DynamicDataDisplay project to my solution, built the solution, and then added the DynamicDataDisplay project as a resource to my project.

Hi, Can i ask you how did you get the code working? which process you did? and which source code you used?
Oct 3, 2013 at 2:16 PM
Too strange i did the same as you did,, first it did not work for several times, and than it started to work :) anyway, thanks for info sharing..

The strange thing is I have the same error. But I just start the project and it happens working properly...

We have faced the same problem. We have download the latest source code "d3future-399ef19cd344".
After opening the example project and try to complier and always get the error "The type 'd3:ChartPlotter' was not found. Verify that you are not missing an assembly reference and that all referenced assemblies have been built."

It took a half day to figure out what is real problem.
We found that all DynamicDataDisplay dlls are target/build with .NET 4.0 and the example project are target/build with .NET 3.5.
After we change example project targets to .NET 4.0 and build, the problem goes away. Hope this finding will help.
