I need the Y Axis Values to be a string (blood pressure)

[Jarrette]

I need help figuring out how to make my y axis values a systolic over diastolic value....

Example: "89/105"

Is there a way to do this?  i'm getting the following error: 

"Telerik.Charting.ChartException: The type of column with name  VitalValue is not numeric"

I was thinking I could do something like this....

rcBloodPressure.PlotArea.YAxis.Appearance.ValueFormat = Telerik.Charting.Styles.ChartValueFormat.None
rcBloodPressure.PlotArea.YAxis.Appearance.CustomFormat = "##/##"

 But it's not working, any suggestions?

OK, problem solved.  In the code I just separate out the systolic and diastolic into separate values and plot two different Y-axis.
