Chart.HasAxis Property

Gets or sets a value indicating whether a specific axis exists on the Chart control.

Namespace: Microsoft.Office.Tools.Excel
Assembly: Microsoft.Office.Tools.Excel (in microsoft.office.tools.excel.dll)

public _HasAxisType HasAxis { get; }

Property Value

true if the specified axis exists on the Chart; otherwise, false.

Use the HasAxis property to hide or show a particular axis on a Chart. The HasAxis property is intended to be used with the following parameters.

Parameter

Description

Index1

One of the XlAxisType values that specifies the axis type. Series axes apply only to 3-D charts.

Index2

One of the XlAxisGroup values that specifies the axis group. 3-D charts have only one set of axes.

If you attempt to use HasAxis without specifying parameters, HasAxis will get a Chart._HasAxisType object that is part of the Visual Studio Tools for Office infrastructure and is not intended to be used directly from your code.

Microsoft Office Excel may create or delete axes if you change the chart type or the AxisGroup property.

Optional Parameters

For information on optional parameters, see Understanding Optional Parameters in COM Interop.

The following code example creates a Chart and then uses the HasAxis property to hide the primary category axis of the chart.

private void TurnOffCategoryAxis()
{
    this.Range["A1", "A5"].Value2 = 22;
    this.Range["B1", "B5"].Value2 = 55;

    Microsoft.Office.Tools.Excel.Chart chart1 =
        this.Controls.AddChart(this.Range["D2", "H12"], 
        "chart1");

    chart1.SetSourceData(this.Range["A1", "B5"], 
        Excel.XlRowCol.xlColumns);
    chart1.ChartType = Excel.XlChartType.xl3DBarClustered;

    chart1.HasAxis[Excel.XlAxisType.xlCategory, 
        Excel.XlAxisGroup.xlPrimary] = false;
}
