Bar chart - color & margin

[Jon Barron]

I'd like to be able to set the margin between bars to zero so there is no gap between them.

I'd like to be able to color each bar differently depending on the value of the item. i.e. if the value is <80, color it red, if it's between 80-100, color it yellow, and if it's >100, color it green. I'm fine if I have to do this programmatically.

Hello Jon Barron,

To be able to set the distance between bars to zero use the ItemWidthPercent property and set it to 100% like this:

this.RadChart1.DefaultView.ChartArea.ItemWidthPercent = 100;

You should also change the LayoutMode property of the AxisX to Auto, Between or Inside according to what you like.

For your second question there is a good help topic here - http://www.telerik.com/help/silverlight/radchart-styling-and-appearance-custom-item-style.html. There is described exactly how to color the bars in a specific color, depending on their value. You can also check this online example - it shows how to apply MVVM pattern to achieve this.
