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

org.jfree.chart.axis.LogAxis.java2DToValue()
Converts a Java2D coordinate to an axis value, assuming that the axis covers the specified edge of the area. @param java2DValue the Java2D coordinate. @param area the area. @param edge the edge that the axis belongs to. @return A value along the axis scale.
