The following members accept/return TimeSpanScaleOptions objects:
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. |
