| 34 | * The <code>CartesianGraph</code> provides the transformation from user to |
---|
| 35 | * physical coordinates. A Cartesian graph has |
---|
| 36 | * horizontal and vertical transforms, from user to physical |
---|
| 37 | * coordinates, that are independent. |
---|
| 38 | * For example, yp = f(yu) and xp = g(xu), where |
---|
| 39 | * f() and g() are the vertical and horizontal transformations. |
---|
| 40 | * Multiple horizontal and vertical, X and Y, axes can be associated with |
---|
| 41 | * a <code>CartesianGraph</code> and their mapping of user to physical |
---|
| 42 | * coordinates is based on the <code>AxisTransform</code>s used. |
---|
| 43 | * The <code>CartesianGraph</code> also provide the support for |
---|
| 44 | * the rendering of data. The specific renderer is chosen based on |
---|
| 45 | * the type of <code>SGTData</code> and the data <code>Attribute</code> used. |
---|
