Hi I can't help much on the 3d front, I have my own issues with the x-axis labeling, but to plot multiple lines you'll need to create a series for each data set and then set that data source on each series. Paul

Hi That fixed it. Many thanks Paul

This is a thread bump as, having upgraded to 0.8.3065.20832, there are still issues with applying 3d templates. This time the issue resides in the resource XAML taken from the sample application where 'X' 'Y' and 'Z' are not found in the type Cylinder: <DataTemplate x:Key="Cylinder"> <cfx3d:Cylinder Cap="Both" X="{Binding Path=X}" Y="{Binding Path=Y}" Width="{Binding Path=W}" Height="{Binding Path=H}" Depth="{Binding Path=W}" Z="{Binding Path=Z}" Material="{Binding Path=View3D.Material}" BackMaterial="{Binding Path=View3D.Material}"/> </DataTemplate> Many thanks Paul

Hi Can anyone point out where I may be going wrong in the attched project? I have a List (Of <a test structure>) being passed to a chart, and setting the .AxisX.Labels.Binding = "Name" as the property requires a string but the chart fails to render the values associated in the list of objects value properties. Many thanks Paul

I will have a go, though at present the actual data on the chart is not important. When will the latest buld be available? I don't want to contact the wpf email address and end up getting the same version again. Thanks Paul

Hi When I attempt to set the template of a chart to change it to a cylinder 3d bar chart via .AllSeries.Template = DirectCast(FindResource("Cylinder"), DataTemplate) , the following exception occurs: System.NullReferenceException was caught Message="Object reference not set to an instance of an object."

hi Thanks for the very quick feedback. One thing to note though, in the previous version I had when such a list was passed to the chart, it would plot (in my case a bar) based on the lengths of the strings. Many thanks Paul

Hi I was wondering if you could tell me which version you are using - having had to revert to 0.8.2957.30556 build, while the hack of setting the ItemSource of the chart to Null does does get me over the immediate exception on the Series.Add, I do get the following exception thrown whan the charts are being displayed / painted: System.NullReferenceException was unhandled Message="Object reference not set to an instance of an object."

Many thanks Paul

Thanks for the information regarding new releases - do you know the average turnaround for responding to that email address? Many thanks Paul

Hi How do I get the lastest version? On my machine the ChartFX DLLs are versioned as 0.8.2957.30556 which is the same as stated in your 'Download Beta' section - this version does not have AxisX.Labels.BindingPath Regards Paul

Hi I'm using Linq to query a data table - it's output returns a Collections.Generic.IEnumerable(Of Object). In your sample app the DataItem object is used to put data values onto the X axis of a bar chart - is it possibel to do the same in my scenario? Many thanks

When can we expect to see updated documentation, inline with the current version as API help file date is somewhat old @ August 2007. Many thanks Paul
