Connecting to Data

The chart control can be bound or unbound. If the control is unbound, provide the values as double values.

When the chart is bound, the values can any data type that can be converted to a double value (including int, double, decimal, string, and so on).

You can set the data display unit. For example, if your data values are in the millions, you can display the data in millions, with a smaller range of values (100,000,000 is represented by 100). The display unit is set by the DisplayUnit property of the ValueAxis class that represents the value axis.
