Description alex 2015-10-12 09:07:11 EDT 
When using cloneSeries it creates a new object and assigns properties from the cloned one. But assign method in subclasses of Series is either not redefined or doesn't copy a lot of fields (in Series too).

For example CustomBar has fields barSizePercent, depthPercent, offsetPercent which are configurable through settings, yet are not copied when cloning.

As a results if you customized and cloned a series almost all settings would be lost.

Test case for Bar series

This test case shows that a clonned serie doesn't copy settings from its original.

Please note that there is a lot of such fields which aren't copied and it is not limited to the Bar class. That's why fixing only these three won't help at all but writing a test case for all cases is too much. Because it's almost every field in almost every subclass of Series.

The simple code below reproduces the problem: 

public static void initializeChart()
 {
    
    tChart1.getAspect().setView3D(false);
    tChart1.getLegend().setVisible(false);
    Bar bar = new Bar(tChart1.getChart());
    Bar  bar1 = new Bar(tChart1.getChart()); 
    bar.setBarWidthPercent(100);
    bar.add(77); 
    bar.add(66);
    bar.add(33); 
    bar.setColor(Color.red);
    bar1 = (Bar) bar.cloneSeries();
 }
