Millisecond

Specifies a millisecond as the measurement unit for date-time values.

Second

Specifies a second as the measurement unit for date-time values.

Minute

Specifies a minute as the measurement unit for date-time values.

Hour

Specifies an hour as the measurement unit for date-time values.

Day

Property Paths

You can access this nested property as listed below:

Remarks

This property is available when the SeriesBase.ArgumentScaleType or SeriesBase.ValueScaleType property is set to DateTime, and the ScaleOptionsBase.ScaleMode property is set to Manual.

DateTimeScaleOptions.MeasureUnit = Quarter DateTimeScaleOptions.MeasureUnit = Year
MeasureUnit_Day MeasureUnit_Month

Note

To access DateTimeScaleOptions, use the AxisBase.DateTimeScaleOptions property.

To define a date-time measurement unit to which the beginning of a diagram’s gridlines and labels should be aligned, use the DateTimeScaleOptions.GridAlignment property.

Example

This example shows how to use DateTimeScaleOptions to reduce the number of visible series points.

Result

The following code configures the axis scale settings to resemble to the chart appearance above:

DateTimeScaleOptions dateTimeScaleOptions = ((XYDiagram)chartControl.Diagram).AxisX.DateTimeScaleOptions;

dateTimeScaleOptions.WorkdaysOnly = true;
dateTimeScaleOptions.ScaleMode = ScaleMode.Manual;
dateTimeScaleOptions.AggregateFunction = AggregateFunction.Average;
dateTimeScaleOptions.MeasureUnit = DateTimeMeasureUnit.Month;
dateTimeScaleOptions.GridAlignment = DateTimeGridAlignment.Quarter;
dateTimeScaleOptions.GridSpacing = 1;
