Bubble Chart + Line Chart

[Chintu Bajaj]

Hello,

Is there a way I can show a bubble chart with a line piercing through the center of each of the bubble?

Sort of combining line chart and bubble chart.

I want to use Silverlight with Telerik or any other control which can make this a possibility.

Thanks,
Chintu

Hello Chintu Bajaj,

You can achieve the desired functionality by defining two separate series -- one line and one bubble:

DataSeries series = new DataSeries();
series.Definition = new BubbleSeriesDefinition() { BubbleSizeRelative = false };
series.Add(new DataPoint(21) { BubbleSize = 80 });
series.Add(new DataPoint(30) { BubbleSize = 30 });
series.Add(new DataPoint(10) { BubbleSize = 50 });

DataSeries series2 = new DataSeries();
series2.Definition = new LineSeriesDefinition();
series2.Add(new DataPoint(21));
series2.Add(new DataPoint(30));
series2.Add(new DataPoint(10));

RadChart1.DefaultView.ChartArea.AxisX.LayoutMode = AxisLayoutMode.Inside;
RadChart1.DefaultView.ChartArea.DataSeries.Add(series);
RadChart1.DefaultView.ChartArea.DataSeries.Add(series2);

Thanks Freddie..  actually I got this working.

I have a follow up question though.. I was trying to have different color per bubble and I had to create a different data series for each of the bubble (to get different color)... is there a way I can set different background color per bubble in the same series based on a  condition?

For eg:
val  between 5 & 10 === Yellow
val  between 10 & 15 === green
etc. etc.

Note: My requirement was to have different size and color.. I could set different size using the DataPoint class but not color.

Thanks,
Chintu

Hi Chintu Bajaj,

You can use the MVVM approach demonstrated here (documentation here). We have attached a sample application to get you started as well.

Hope this helps.
