setCluster + hide legendbox + hide data issues on legend

Question

Hello,

 

I found a bug on a specific case, using cluster without legendbox.

 

First, we activate Cluster, 5 series of severals points, disabling legendbox (we can have very long titles)

All OK, it displays titles in front of series.

 

If I hide some series, hen, it seems to not consider the hiding series to compute legend place, they are placed on same position, just hidden for the hidden series.

 

2 screenshots:

 

All show : http://awesomescreenshot.com/00d409naa6

B,C,D hidden : http://awesomescreenshot.com/0e5409oofb

Ex:

 

HTML:

<div id="graph" style="width:600px;height:400px;display:block;margin-top: 200px;"></div>

JS (tested on 7.1.5044 and 7.2.5289):

        var chart1 = new cfx.Chart();

        chart1.getView3D().setCluster(true);

        chart1.getView3D().setPerspective(40);
        chart1.getLegendBox().setVisible(false);

        var data = [
            { a: 1, b: 2, c: 3, d: 2, e: 10,label:'A1' },
            { a: 2, b: 3, c: 1, d: 3, e: 11,label: 'A2' },
            { a: 1, b: 2, c: 3, d: 1, e: 30,label: 'A3' },
            { a: 1, b: 3, c: 2, d: 2, e:40,label: 'A4' },
            { a: 3, b: 2, c: 1, d: 3, e:10,label: 'A5' },
        ];
        
        chart1.setGallery(cfx.Gallery.Area);
        chart1.setDataSource(data);
      
        var ok = false;
        var f = function (){
            ok = !ok;
            chart1.getSeries().getItem(1).setVisible(ok);
            chart1.getSeries().getItem(2).setVisible(ok);
            chart1.getSeries().getItem(3).setVisible(ok);
            setTimeout(f,2000 );
        };
        f();
        chart1.create(document.getElementById('graph')); 
        


It automatically toggles hide/show for middle series,

 

Hide/Show will be a manual action on screen, all series must be shown at start.

 

Thank you for a quick patch!
