public DateTimeGridAlignment GridAlignment { get; set; }Property Value
| Type | Description |
|---|---|
| DateTimeGridAlignment | A DateTimeGridAlignment enumeration value that represents the measurement unit to which the beginning of an axis’s gridlines and labels should be aligned. |
Available values:
| Name | Description |
|---|---|
| Millisecond | Specifies a millisecond as the date-time unit to which axis gridlines should be aligned. |
| Second | Specifies a second as the date-time unit to which axis gridlines should be aligned. |
| Minute | Specifies a minute as the date-time unit to which axis gridlines should be aligned. |
| Hour | Specifies an hour as the date-time unit to which axis gridlines should be aligned. |
| Day | Specifies a day as the date-time unit to which axis gridlines should be aligned. |
| Week | Specifies a week as the date-time unit to which axis gridlines should be aligned. |
| Month | Specifies a month as the date-time unit to which axis gridlines should be aligned. |
| Quarter | Specifies a quarter of a year as the date-time unit to which axis gridlines should be aligned. |
| Year | Specifies a year as the date-time unit to which axis gridlines should be aligned. |
Property Paths
You can access this nested property as listed below:
| Object Type | Path to GridAlignment |
|---|---|
| AxisBase |

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.
| GridAlignment = Month, MeasureUnit=Month | GridAlignment = Quarter, MeasureUnit=Month |

To maintain date-time values at different detail levels, use the DateTimeScaleOptions.MeasureUnit property.
Example
This example demonstrates how an axis’ date-time and numeric options can be customized, depending on the ScaleType defined for a series’ arguments and values.
using System;
using System.Windows.Forms;
using DevExpress.XtraCharts;
// ...
namespace FormatAxisLabels {
public partial class Form1 : Form {
public Form1() {
InitializeComponent();
}
private void Form1_Load(object sender, EventArgs e) {
// Create an empty chart.
ChartControl chartControl1 = new ChartControl();
// Create a bar series and add points to it.
Series series1 = new Series("Series 1", ViewType.Bar);
series1.Points.Add(new SeriesPoint(new DateTime(2009, 1, 1), new double[] { 26.25 }));
series1.Points.Add(new SeriesPoint(new DateTime(2009, 2, 1), new double[] { 16.52 }));
series1.Points.Add(new SeriesPoint(new DateTime(2009, 3, 1), new double[] { 22.21 }));
series1.Points.Add(new SeriesPoint(new DateTime(2009, 4, 1), new double[] { 15.35 }));
series1.Points.Add(new SeriesPoint(new DateTime(2009, 5, 1), new double[] { 24.15 }));
// Add the series to the chart.
chartControl1.Series.Add(series1);
// Hide the legend (if necessary).
chartControl1.Legend.Visibility = DevExpress.Utils.DefaultBoolean.False;
// Set the scale type for the series' arguments and values.
series1.ArgumentScaleType = ScaleType.DateTime;
series1.ValueScaleType = ScaleType.Numerical;
// Cast the chart's diagram to the XYDiagram type, to access its axes.
XYDiagram diagram = chartControl1.Diagram as XYDiagram;
// Define the date-time measurement unit, to which the beginning of
// a diagram's gridlines and labels should be aligned.
diagram.AxisX.DateTimeScaleOptions.GridAlignment = DateTimeGridAlignment.Day;
// Define the detail level for date-time values.
diagram.AxisX.DateTimeScaleOptions.MeasureUnit = DateTimeMeasureUnit.Month;
// Define the custom date-time format (name of a month) for the axis labels.
diagram.AxisX.Label.TextPattern = "{V:MMMM}";
// Since the ValueScaleType of the chart's series is Numerical,
// it is possible to customize the NumericOptions of Y-axis.
diagram.AxisY.Label.TextPattern = "{V:C1}";
// Add a title to the chart (if necessary).
ChartTitle chartTitle1 = new ChartTitle();
chartTitle1.Text = "Axis Scale Types";
chartControl1.Titles.Add(chartTitle1);
// Add the chart to the form.
chartControl1.Dock = DockStyle.Fill;
this.Controls.Add(chartControl1);
}
