I am trying to chart activity from a helpdesk. I am using a Range Chart with number of tickets opened in a period as the Low and number of tickets closed in a period as the High. While this seems to work (even though the Low can exceed the high), I need a way to color the area between the high and low points to signify that the net number of tickets opened or closed in a day is positive or negative. If you look at the attached chart, it pretty much does what I am looking for. Any way the Telerik controls can do that?
