Examples of org.jfree.chart.axis.ValueAxis.valueToJava2D()

org.jfree.chart.axis.ValueAxis.valueToJava2D()
Converts a data value to a coordinate in Java2D space, assuming that the axis runs along one edge of the specified dataArea.
Note that it is possible for the coordinate to fall outside the area. @param value the data value. @param area the area for plotting the data. @param edge the edge along which the axis lies. @return The Java2D coordinate. @see #java2DToValue(double,Rectangle2D,RectangleEdge)
