Yup, that worked. Thanks for pointing in the right direction. This is what I did:

****

Style style = new Style(typeof(Control));

Setter st1 = new Setter(Control.OpacityProperty,0);

style.Setters.Add(st1);

((StackedBarSeries)this.chrtXXX.Series[0]).SeriesDefinitions[0].DataPointStyle = style;

****

Srini,

Yes, that's the way to remove a SeriesDefinition from the collection. I'm not sure I understand your scenario, but here's an alternate approach: set the DataPointStyle of the SeriesDefinition you want to hide to a custom Style that defines an empty Template. This should immediately be applied to each of the relevant DataPoints and they should disappear. When you want them to come back, just do a ClearValue on that same DataPointStyle property and the DataPoints should come back. :)

Hope this helps!

Delay,

I tried removing the series definition, but here's the problem. There are two series definitions, sd1, sd2, one stacked on top of the other. Lets say one value of sd1 starts at 0 and ends at 100 and the sd2 at the same point starts at 100 and ends at 150. If I remove sd1, then sd2 now falls down and starts at 0. I want sd2 to stay at 100.

Also, I used the following way to remove the sd - ((StackedBarSeries)this.chrtXXX.Series[0]).SeriesDefinitions.Remove(sd1);

Is this the right way?

Delay,

Thanks for the prompt reply. Let me try that and I'll let you know how it worked for me.

Srini,

Removing the SeriesDefinition from the StackedSeries's SeriesDefinitions collection (and adding it back when you want it to display again) is probably what you want to do here.

I'm using the stacked bar series and I have two series definitions in that. I want to set the opacity of the first series to 0. But I'm unable to do it. Basically I want to hide one of the two series that make up my stacked bar series. How to do that?

Andy,

Sorry, I don't think I understand the question. A pre-compiled version of the Silverlight/WPF Toolkit's DataVisualization assembly specifically targetting WPF 4 can be found inside the ZIP linked to by the post above: cesso.org/.../SilverlightWpfDataVisualization.zip. I hope that's what you're looking for!

Trying to use the built in 4.0 WPF charting via System.Windows.Controls.DataVisualization.Charting but cant find them except in the WPF Toolkit which is only 3.5.

Joe,

It sounds like you copied that XAML from my ChartBuilder sample (more information: blogs.msdn.com/.../click-your-way-to-great-silverlight-charts-live-chartbuilder-sample-and-source-code.aspx). In that case, the ObservableObjectCollection reference is to a class that's part of the ChartBuilder assembly and that's why it's not resolving successfully in your application. All it really is is a trivial subclass of ObservableCollection<object>, so it'll probably be easiest for you to just create a subclass of that in your project and reference that instead.

Hope this helps!
