Returns the specified X value of a series in the chart object (for XY-Scatter and XY-Curves).

    double object.GetSeriesXValue( int index, int valueindex )

#### Arguments

object
  Required. A Chart object.
index
  Required. An integer value that specifies the zero-based index of the series in the chart object.
valueindex
  Required. An integer value that specifies the zero-based index of the X value in the series specified by index.

#### Return Value

A floating-point number containing the X value spedified by valueindex in the data series specified by index.

#### Remarks

If the index argument refers to a series that does not exist in the chart object, the GetSeriesXValue method raises an invalid series index error.

If the valueindex argument refers to a X value that does not exist in the specified series, the GetSeriesXValue method raises an out of bounds error.

- index must be superior or equal to 0.
- index must refer to an existing series.
- valueindex must be superior or equal to 0.
- valueindex must be strictly inferior to GetValuesCount.

Note: This method is available when manipulating XY data series required for displaying XY-Curves and XY-Scatter. Note that the Chart type (ie: bar, column, line, etc.) is defined in the Swiff Chart style file (.scs) which must be loaded via the LoadStyle method.

#### JSP Code Sample

The following JSP code illustrates use of the GetSeriesXValue method.

    // Set the series
    chart.SetDataFromTxtFile("C:\\myData.txt");

    // Retrieve the number of series stored in the chart object
    int n_series= chart.GetSeriesCount();
    int n_categories= chart.GetValuesCount();

    if( n_series == 0 )
      out.println( "No series available<br>" );
    else
      {
      // Enumerate the series stored in the chart object
      for( int i = 0; i < n_series; ++i )
        {
        // Enumerate the XY points of the series
        for( int j = 0; j < n_categories; ++j )
          {
          String str= "Series[" + i + "][" + j + "]=";
          str= str + "(" + chart.GetSeriesXValue(i,j);
          str= str + ",";
          str= str + chart.GetSeriesYValue(i,j) + ")<br>";
          out.println( str );
          }
        }
      }
