Spline Charts

Updated over 1 year ago

Spline charts allow you to take a limited set of known data points and approximate intervening values.  In practice you define a series of chart items with X/Y values and RadChart does the rest. 

To create a simple vertical Spline Chart set the SeriesOrientation property to Vertical. Set the RadChart DefaultType property or ChartSeries.Type to Spline. Create a series and add chart items with Y or X and Y values.

To create a simple horizontal Spline Chart set the SeriesOrientation property to Horizontal. Set the RadChart DefaultType property or ChartSeries.Type to Spline. Create a series and add 3 or more chart items with X and Y values.

YValue	XValue
20	50
50	-10
70	100
80	50

Another example showing the same Y data points as above, but with no X values defined displays an automatic even progression over the X axis.

YValue
