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

object.GetSeriesYValue( index, 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 Y value in the series specified by index.

Return Value

A floating-point number containing the Y 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 GetSeriesYValue method raises an out of bounds error.

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

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.

JScript Code Sample

The following JScript code illustrates use of the GetSeriesYValue method.

//Load a style for generating XY Curves
chart.LoadStyle( "C:\myXYCurveStyle.scs" );

//Load the series and display the result
chart.SetSeparators( ";", true );
chart.SetDataFromQuery();

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

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