EcGraph Demo14.   Data points numbered sequentially

• Data points numbered sequentially.
• Showing two data series of random points plotted as sequential numbers and letters

The VB code used to generate the above graph...

Public Sub Demo14(ecGraph1 As ecGraph)
  'Data points numbered sequentially
  Dim i, X As Double, Y As Double
  With ecGraph1
    Call .Reset 'Always call "Reset" first to clear the page
    
    'Start a new graph on the page..
    Call .NewGraph("Data points numbered sequentially")
    
    'Start a new data set on the graph, and add random points..
    Call .NewDataSet("Data series 1")
    Call .SymbolStyle(-1, , , , , , , , , , , , "Font=Courier New")
    For i = 1 To 18
      X = i
      Y = Sqr(i) - Rnd(i) / 3
      Call .AddDataPoint(X, Y)
    Next i
    
    'Second data set for this graph
    Call .NewDataSet("Data series 2")
    Call .SymbolStyle(-2, , , , , , , , , , , , "Font=Courier New")
    For i = 2 To 18
      X = i
      Y = Log(i) / 2 - Rnd / 4
      Call .AddDataPoint(X, Y)
    Next i
    
    Call .Refresh 'Always end with "Refresh"
  End With
