RE: Charting with WPF and Linq

[Greg Keogh]

Try these WPF & Silverlight chart controls..

http://www.visifire.com/

 

I've been using Visifire for a year now and an SL3 app and it worked very
well. You just feed it arrays of data series and points and it produces
impressive charts with little effort. We even drilled down and adjusted the
shapes of data points, series colours, etc with the countless properties.

 

We're upgrading to C1 charting now, mainly because it has radar charts,
which are curiously missing from Visifire.

RE: Charting with WPF and Linq

Well, in the end, I've managed to get it working using the series DataContext.

I'm still operating very much in the C# paradigm, and still (even in VS2010) 
find working in XAML a frustrating experience. If you're not doing it every 
day, all day, it is quite hard to gain much fluency, and too easy to fall back 
on C# code behind in the name of getting it done. And it seems that once you've 
done it for one thing, you are pretty much stuck then, as all the neat XAML 
shortcuts I could have taken seem unavailable to me now that so much else is 
being done in code-behind.

I'd like to see a guide to refactoring forms from C# to XAML, explaining, for 
instance, how to take data bound controls that are populated from C# and port 
it into XAML.

Anyway...

Dylan.

I have a .NET 3.5 WPF app (working on it in VS2010).

On one of the windows, is a grid that is populated with data from an in-memory 
LINQ to SQL object (the hard way, in code instead of in bindings.)

I am trying to drop a simple line graph underneath it, and am struggling to 
find a good example.

Most web sites I've found are either talking about creating a chart completely 
from scratch in XAML. I haven't seen any examples of creating a chart and 
populating it via C#. I'm using the WPF Chart control, which seems pretty good.

My datasets are pretty small, so I was thinking I'd just create a 
PointCollection and populate it with Point objects that represent each data 
point, but since my graph is a series over time, I can't see how I get a value 
(Y) and date (X) value into a point in .NET 3.5. I would then assign the 
PointCollection to a Series that I've already created, and set the minimum and 
maximum values for the Axes accordingly. (My X axis is already set up with 
dates, and that seems to work. Just can't get the Point to accept a date.)

I feel like I'm on the wrong track and there should be some better way. Can I 
just use the DataContext of the chart directly?

Am I missing something basic? There doesn't seem to be any good examples of 
doing this anywhere that I can find.

Cheers,

Dylan Tusler
