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 );
      }
    }
  }
