Namespace: GlobFX.SwiffChartGenerator
Assembly: GlobFX.SwiffChartGenerator (in GlobFX.SwiffChartGenerator.dll)

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

Public Function GetSeriesValue( index As Integer, valueindex As Integer ) As Double

public double GetSeriesValue( int index, int valueindex ); 

Arguments

index

An integer value that specifies the zero-based index of the series in the chart object.

valueindex

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 ValuesCount.

Code Sample

The following code illustrates use of the GetSeriesValue method.

chart.SetDataFromTxtFile("C:\\myData.txt")

' Retrieves the number of series stored in the chart object 
Dim n_series As Integer = chart.SeriesCount
Dim n_categories As Integer = chart.ValuesCount

If n_series = 0 Then
  Me.Response.Write( "No series available<br>" )
Else
  ' Enumerate the series stored in the chart object 
  Dim i As Integer  
  Dim j As Integer  
  For i = 0 To n_series - 1
    For j = 0 To n_categories - 1
      Me.Response.Write( "Series[" + i + "][" + j + "]=" + chart.GetSeriesValue(i,j) + "<br>" )
    Next
  Next
End If

chart.SetDataFromTxtFile("C:\\myData.txt");

// Retrieves the number of series stored in the chart object 
int n_series= chart.SeriesCount;
int n_categories= chart.ValuesCount;

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