Joel Barsotti,

The "staggering" behavior you mention didn't seem to make the same sense for stacked series, so they use the same "stacking" behavior as is used for different SeriesDefinitions. As far as I know, this works properly, but it sounds like maybe you think there's a bug as well?

One thing I was using in the old column/bar stack was that it would squish multiple columns into the same category.

Now it seems to try and do a stack column/bar but with data from several data series, so instead it overlaps based on the series index.

Timmy,

The WPF Toolkit hasn't released a new version since the April 2010 Silverlight Toolkit was released with stacked series support, so what's in the current download is not the latest stuff. However, you can get the latest version of the Data Visualization assembly (binaries and code) for all supported platforms as part of my Development Release: blogs.msdn.com/.../phone-y-charts-silverlight-wpf-data-visualization-development-release-4-and-windows-phone-7-charting-sample.aspx

Hope this helps!

Hi Delay,

it is possible that StackedSeries removed from WPF Toolkit, because I get the error that StackedBarSeries not exists in 'clr-namespace ...DataVisualization.Toolkit'.

I used v3.5.40128.1.

Hi David, thanks for the tipp and the additional explanations. As you suggested, I derived from StackedBarSeries. It works perfectly fine and finally gives me the flexibility to mix stacked series with other series now dynamically. Regards, Andreas

Andreas,

The DefinitionSeries.SeriesDefinitions collection-typed property is deliberately *not* a DependencyProperty (for the same reason that Chart.Axes isn't; you can read more about why here: cesso.org/.../DTDPDEFSHARE). Because Binding only works with DependencyProperties, I suspect this is the reason for the trouble you've had so far.

That said, the Chart.Series property is the same kind of thing, so I'd expect that if you take the same approach Beat writes about in the link you reference (subclassing and adding a DependencyProperty for Binding), it would work for *this* scenario as well (except in this case you'll subclass StackedBarSeries instead of Chart).

If you try this, I'd love to hear how it works out!

(But if not, then you should always be able to create the SeriesDefinitions in code - you just won't be able to leverage Binding the same way.)

Hi David,

Very informative - as always. I am currently binding a dynamic amount of series to a chart as described by Beat Kiener in his Blog blog.thekieners.com/.../databinding-multi-series-charts.

Now I want to include support for Stacked Bars as well and therefore would like to ask if there is a way to bind a list of SeriesDefinitions to e.g. a StackedBar. I tried it using the SetriesDefinitions attribute of the StackedBarSeries but always end up with an error (either XAML parsing or Child is already Element of another...). Can you comment on that? Thanks!

Regards,

Andreas

Thanks for the advice - I'll give it a try and let you know if i land anything worth sharing.

Kevin,

In the current bits, the stacked series will not group, sorry about that. If it's really important to you and you don't mind writing some code, some grouping logic is already present in the non-stacked series. It doesn't seem like it should be too, too difficult to pull that out and apply it here. Alternatively, you might consider a custom CategoryAxis implementation that works with a single StackedSeries and creates the grouping by laying similar things out close to each other. As I think about it more, this may actually be better because it'll give you more sensible category labels, too - and it shouldn't require modifying the series at all.

Hope this helps!

Hi Delay -

Quick question regarding the stacked series. i was wondering if it is possible to group the stacks. so, to use the above example, there would be an Alice column for 2009 and an Alice column for 2010, and so on with Bob and Eve.

Thanks

Kevin
