Returns the specified value of a series in the chart object.

float object->GetSeriesValue( 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 value in the series specified by index.

Return Value

A floating-point number containing the data 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 GetSeriesValue method raises an invalid series index error.

If the valueindex argument refers to a data value that does not exist in the specified series, the GetSeriesValue 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().

PHP Code Sample

The following PHP code illustrates use of the GetSeriesValue method.

$chart->SetDataFromQuery();

// Retrieves the number of series stored in the chart object 
$n_series= $chart->GetSeriesCount();
$n_categories= $chart->GetValuesCount();

if( $n_series == 0 )
  print("No series available<br>");
else
  {
  // Enumerate the series stored in the chart object 
  for( $i= 0; $i < $n_series; ++$i )
    for( $j= 0; $j < $n_series; ++$j )
      print("Series[" . $i . "][" . $j . "]=" . $chart->GetSeriesValue($i, $j) . "<br>");
  }
