Our chartview does not have a built-in true-false series. We have a similar control in our Sparklines
set, the RadWinLossSparkline.
With the chartview you can use a work around. You can set the ValueBinding property of the series to be a GenericDataPointBinding<YourDataItem, int> and use a ValueSelector that returns a 0 when the value is false, and returns 1 when the value is true. If you are using bar series, you may want to return -1 if the value is false, this highly depends on the desired results. You may need to set a static Minimum and Maximum for the axis. If you want to see "Ture" and "False" labels instead of "1" and "-1" labels on the axis, you can use a LabelTemplate or the LabelTemplateSelector to adjust a desired look.
I hope this inormation helps. Let us know if you need more information.
