Sspecifies the format of the chart values when the axis represents floating point values. If the axis represents date time values, the  DateTimeFormat property specifies the format of the chart values. The two format properties are used by the FormatValue method to return the proper string representation of a chart value. Use the IsDateTime method to determine if the axis is displaying date time values.
