de.progra.charting.CoordSystem
| CoordSystem | | public class CoordSystem extends AbstractRenderer (Code) | | This class defines a coordinate system. The CoordSystem class computes
an AffineTransform for each y-axis, which translates the user space
coordinates (ie. the data value coordinates) into pixel space coordinates.
These AffineTransform classes make the PixelToPointTranslator obsolete,
since it provides more flexibility. getDefaultTransform always
computes the default transformation, whereas you can set another
transformation via setTransform. This will be used to implement
zooming and panning in the Swing classes.
All classes incl. this one, which render data will use the transformations
to translate the coordinates. The transformations are not set up on
instantiation of a CoordSystem, instead they're computed when setBounds
is called, because they need this information of course. Afterwards you
can set your own transformation or even better you can manipulate the
existing ones by pre- or postconcatenating another AffineTransform.
