TimeSpanScaleOptions.MeasureUnit Property
Gets or sets the detail level for time-span values.
Namespace: DevExpress.XtraCharts
Assembly: DevExpress.XtraCharts.v19.2.dll
Declaration
public TimeSpanMeasureUnit MeasureUnit { get; set; }Public Property MeasureUnit As TimeSpanMeasureUnitProperty Value
| Type | Description |
|---|---|
| TimeSpanMeasureUnit | A value that represents the axis detail level. |
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.
Examples
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. |
