TimeSpanScaleOptions.MeasureUnit Property

Gets or sets the detail level for time-span values.

Namespace: DevExpress.XtraCharts

Assembly: DevExpress.XtraCharts.v21.2.dll

Declaration

public TimeSpanMeasureUnit MeasureUnit { get; set; }

Property Value

Type Description
TimeSpanMeasureUnit

A value that represents the axis detail level.

Available values:

Name Description
Millisecond

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

Second

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

Minute

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

Hour

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

Day

Specifies a day as the measurement unit for time-span values.

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 TimeSpan, and the ScaleOptionsBase.ScaleMode property is set to Manual.

TimeSpanScaleOptions.MeasureUnit = Minute TimeSpanScaleOptions.MeasureUnit = Hour

Note

To access TimeSpanScaleOptions, use the AxisBase.TimeSpanScaleOptions property.

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

Example

The following example shows how to group minute-by-minute data into data points with a greater measurement unit (“Hour”).

To do this, you can use the following code:

private void Form1_Load(object sender, EventArgs e) {
    XYDiagram diagram = chartControl1.Diagram as XYDiagram;
    if (diagram != null) {
        diagram.AxisX.TimeSpanScaleOptions.ScaleMode = ScaleMode.Manual;
        diagram.AxisX.TimeSpanScaleOptions.MeasureUnit = TimeSpanMeasureUnit.Hour;
        diagram.AxisX.TimeSpanScaleOptions.AggregateFunction = AggregateFunction.Average;
        diagram.AxisX.TimeSpanScaleOptions.GridSpacing = 6;
        diagram.AxisX.TimeSpanScaleOptions.GridAlignment = TimeSpanGridAlignment.Hour;
    }             
}

The example uses the following API members:

Member Description
ScaleOptionsBase.ScaleMode Gets or sets the scale mode for an axis.
TimeSpanScaleOptions.MeasureUnit Gets or sets the detail level for time-span values.
ScaleGridOptionsBase.AggregateFunction Gets or sets the value indicating the aggregate function that should be used to relieve data.
ScaleGridOptionsBase.GridSpacing Gets or sets the interval between grid lines and major tickmarks.
