Examples of org.jfree.chart.axis.ValueAxis.java2DToValue()

org.jfree.chart.axis.ValueAxis.java2DToValue()
Converts a coordinate in Java2D space to the corresponding data value, assuming that the axis runs along one edge of the specified dataArea. @param java2DValue the coordinate in Java2D space. @param area the area in which the data is plotted. @param edge the edge along which the axis lies. @return The data value. @see #valueToJava2D(double,Rectangle2D,RectangleEdge)
