uur = history.getBar( ins, Period.ONE_HOUR, kaart.getSelectedOfferSide(), i );
            ding = kaart.getChartObjectFactory().createRectangle( 
                "SemperUur_" + Integer.toString(i), 
                uur.getTime(), 
                uur.getOpen() , 
                uur.getTime() + Period.ONE_HOUR.getInterval(), 
                uur.getClose() 
            );
            if( uur.getOpen() < uur.getClose() ){
                ding.setColor( Color.green );
            }else{
                ding.setColor( Color.red );
            }
            ding.setLineStyle( LineStyle.SOLID );
            ding.setLineWidth( 0f );
            ding.setLocked( true );
            ding.setMenuEnabled( false );
            ding.setTooltip( "" );
            ding.setText( "" );
            kaart.addToMainChart( ding );

All works fine. Now i want to remove the label.

There is a property IsLabelEnabled(), but that only gives back a boolean. I want to set LabelEnabled( false );

How?

Thanks

You can do it with ObjectListeners.
Take a look on the following wiki page for examples:

That is quite a workaround for something that should be simple.

The given example is outdated. Deprecated methods.

Do you want the ability to remove the size of a rectangle in bottom right corner?

Nope: the rectangles are drawn every hour and have fixed sizes and positions. I just want to get rid of the labels.

That's what you want to remove, right?

Right. Thanks for the help. The rectangles are drawn with:

thing = chart.getChartObjectFactory().createRectangle( ...

Currently it's impossible to remove this information, but we will add the possibility in near future.

Thanks.
