132 Scaling and Coordinate Systems

Dim xData() As Double
Dim yData() As Double
= {1000,2000,3000,4000,5000,6000,7000,8000,9000}
= {10, 22, 33, 44, 55, 46, 33, 25, 14, 9}
Dim dataset As ElapsedTimeSimpleDataset = New ElapsedTimeSimpleDataset (“Sales”,
xData, yData)
Dim simpleScale As ElapsedTimeCoordinates = new ElapsedTimeCoordinates ()
simpleScale.AutoScale(dataset)
simpleScale.SetScaleStartY(0)
simpleScale.SetScaleStopY(100.0)
The auto-scale methods that use an array of datasets to determine the proper range are
very similar.
