Remarks

Dates are stored in ChartData objects as numbers called serial values. A serial value is an integer that is the number of elapsed days from the first day in the date system. The SpreadsheetControl supports the 1900 and 1904 date systems for serial values.

When chart data is created using the FromDateTime method, the ChartData.BooleanValue and ChartData.IsNumeric properties return true.
