This icon is not a part a chart. It’s implemented with Vaadin menubar:

MenuBar tools = new MenuBar();
MenuItem root = tools.addItem("", FontAwesome.COG, null);
root.addItem("Configure", new Command() {
  public void menuSelected(final MenuItem selectedItem) {"Not implemented in this demo");

Many thx for your help!!!
