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>");
      }
