TimeSpanScaleOptions Class

Settings of a scale when its type is time-span.

Namespace: DevExpress.XtraCharts

Assembly: DevExpress.XtraCharts.v19.2.dll

Declaration

public class TimeSpanScaleOptions :
    ScaleOptionsBase,
    ITimeSpanScaleOptions,
    IScaleOptionsBase<TimeSpanMeasureUnitNative>,
    IScaleOptionsBase
Public Class TimeSpanScaleOptions
    Inherits ScaleOptionsBase
    Implements ITimeSpanScaleOptions,
               IScaleOptionsBase(Of TimeSpanMeasureUnitNative),
               IScaleOptionsBase

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.
