java - How to turn off shapes in YIntervalRenderer? -

found no way t turn off shapes accessing renderer itself.

renderer.setseriesshape(0, null); 

disables series shape, causes shapes supplier come.

renderer.setautopopulateseriesshape(false); 

disables supplier, causes default shape draw.

renderer.setbaseshape(null); 

causes exception since null not allowed here parameter.

so turn shapes off? may in plot or chart object? can't find.

you can supply empty shape series:

yintervalrenderer r = new yintervalrenderer(); r.setseriesshape(0, new rectangle());
