You can define a coordinate system to any range you want; you do not have to use the auto-scaling. This is all discussed in Chapter 4 - Scaling and Coordinate Systems.
double xMin = -5;
double xMax = 15;
double yMin = 0;
double yMax = 105;
CartesianCoordinates simpleScale;
simpleScale = new CartesianCoordinates(xMin, yMin, xMax, yMax);
It may be that you want to first auto-scale, and then change one or more of the minimum or maximum values. Again, Chapter 4 discusses this.
double [] xData = {2,3,4,5,6,7,8,9};
double [] yData = { 22, 33, 44, 55, 46, 33, 25, 14};
SimpleDataset dataset = new SimpleDataset("“Sales", xData, yData);
CartesianCoordinates simpleScale = new CartesianCoordinates();
simpleScale.autoScale(dataset);
simpleScale.setScaleStartY(20);
Fixing Y-Axis to a certain range of values...
