    out int Arg1,
    out int Arg2
)

Parameters

• X
  Type: System.Int32
  The x-coordinate of the chart element.

• Y
  Type: System.Int32
  The y-coordinate of the chart element.

• ElementID
  Type: System.Int32
  When the method returns, this argument contains the XlChartItem value of the chart element at the specified coordinates. For more information, see the Remarks section.

• Arg1
  Type: System.Int32
  When the method returns, this argument contains information related to the chart element. For more information, see the Remarks section.

• Arg2
  Type: System.Int32
  When the method returns, this argument contains information related to the chart element. For more information, see the Remarks section.

Remarks

This method is unusual in that you specify values for only the first two arguments. Microsoft PowerPoint fills in the other arguments, and your code should examine those values when the method returns.

The value of ElementID after the method returns determines whether Arg1 and Arg2 contain any information, as shown in the following table.

The following table describes the meaning of Arg1 and Arg2 after the method returns.

Argument	Description
AxisIndex	Specifies whether the axis is primary or secondary. Can be one of the following XlAxisGroup constants: xlPrimary or xlSecondary.
AxisType	Specifies the axis type. Can be one of the following XlAxisType constants: xlCategory, xlSeriesAxis, or xlValue.
DropZoneType	Specifies the drop zone type: column, data, page, or row field. Can be one of the following XlPivotFieldOrientation constants: xlColumnField, xlDataField, xlPageField, or xlRowField. The column and row field constants specify the series and category fields, respectively.
GroupIndex	Specifies the offset within the ChartGroups collection for a specific chart group.
PointIndex	Specifies the offset within the Points collection for a specific point within a series. A value of –1 indicates that all data points are selected.
SeriesIndex	Specifies the offset within the Series collection for a specific series.
ShapeIndex	Specifies the offset within the Shapes collection for a specific shape.
TrendlineIndex	Specifies the offset within the Trendlines collection for a specific trendline within a series.
