See Telerik column chart demo here:
http://demos.telerik.com/aspnet-ajax/htmlchart/examples/charttypes/columnchart/defaultcs.aspx
Notice the labels above each column, such as "25000 sales". Now notice in the declarative code how this label is set:
<LabelsAppearance DataFormatString="{0} sales" Position="OutsideEnd"></LabelsAppearance>
I either need to set DataFormatString programmatically, or (better yet) I need to set it to the value of a column in my dataset from sql server. This column's data is not on the chart currently because I ONLY want that column's data used at the label at the top of each column. I can't figure out how to do either. How is it done?
