As seen in image, the data labels are overlapping and making the data difficult to read. Anybody know how to sort this?
Have now updated the question as I have changed the PieLabelStyle to Outside and in the picture you can see in the design view above it acknowledges this however when I preview the chart it remains on the inside! (See image 3 link below)

Technet has a nice piece on this:
The secret is in the Properties pane under the Custom Attributes section:
A good solution is to sort the pie chart between small and big pieces. I posted a script that helps with this issue:

In a video of the DevExpress Chart Demo (see attached image and link below) out on YouTube... the "Large DataSource" demo seems to have some sort of "range" bar at the top where you can see an overview of the data and adjust the left and right of the range and drag the range left and right as well. In the current version of DevExpress the demo doesn't have this feature. Does anyone know how to implement it... or at least what it is officially called so I can look it up in the documentation.
Also, if anybody knows, is there is source code for this demo?
The actual video I'm talking about is here: https://www.youtube.com/watch?v=HmA6vANrKKk
some sort of "range" bar at the top
Your screenshot is demonstrates the RangeControl, which provides a data range selection functionality.
ChartControl on your screenshot is bound to the RangeControl via the RangeControl.Client property.
My goal is to have a diagram which look like this
Each arrow should be a one dimensional chart, where point are displayed (colors and point size depends on some values)
I'm building my own chart system because I spent a few hours looking for one which allow to custom markers (size and colors, and maybe even shape) but I couldn't find one.
Actually the only one I found is dynamic data display 2.0 which is only proposed in Silverlight.
My biggest problem is the two curving chart I have to do at the top of the diagram.
I tried to use PathListBox control, but because it's a listBox, I couldn't display items at fixed X position (like using a chart).
I'm not asking for a full perfect solution, but can someone give me advices, or clues ?
How would you manage to do something like that ?
It should only be a XAML work here, because all the data are already ready in a ListCollectionView (i'm using MVVM).
Thank you !
we want to make application like silverlight showcase Mapview
where we can search by different category on left hand side panel or people can select country or region on map. can anyone suggest some sample or guidelines to implement this?
Thanks
Given the complexity and obvious expense, I would be really impressed if anything like that was released as a sample (Microsoft are you listening?). It requires a lot of data to drive it.
I have been involved in creating a Xaml World map from scratch (below) and that alone took nearly a day for a stylised polygon version (no fine detail)....
Quoting myself: "You import a map as a background image and use the pen tool to dot-to-dot trace around the country. Combine all those path segments into a single path. Then create a separate poly-path for each state (close them to allow for a fill)."
Once you create them you can name the individual country polygons and connect up mouse logic to make them all glow on mouse over or change colour on press etc.
Basically all the other stuff on that screen are user controls and custom controls. Work out the behaviour you want and create controls to suit your own needs.
I want to set a toolTip on each of the data Points of the pie charts.
I know how to do that, but as you can see in the attached picture,
the toolTips look different according to the data points directions.
Someone has an idea how can I do that ?
If you're using the WPF/Silverlight toolkit charts, see Bea Stollnitz's posts on that subject:

Her posts are very well-written - you should be able to find what you need there.
If you are looking for more advanced charts then you should give Telerik a try. Here is a demo page with several chart samples (that can include ToolTips).
Hii
Can anyone tell me how can I show percentage on the piechart....
The percentage is seen on mouseover event but I dont know how to show
the percentage on the piechart's slices....
If you are looking to put labels on the chart itself (instead of tooltip), take a look at this great blog post by WPF guru Bea Stollnitz.
It shows how to do this, in many different modes, and explains not only how, but why.
Take a look at amCharts Bundle for WPF. Pie chart supports labels on the slices, outside connected labels and includes an algorithm to prevent label overlapping.
I've just followed this tutorial (just to make sure) and I get the percentages of each slice as tooltip on mouse over by default.
If you post your code we might be able to spot if there's a problem with it.
You can use labelFunction in mx:PieSeries, and lableFunction look like that
private function pieSeries_labelFunc(item:Object, field:String, index:Number, percentValue:Number):String
{
return StringUtil.substitute("{0} ({1}%)",item.description,percentValue.toFixed(1));
}
Where description is the label that you want to see.
feel free to ask any question.
