Pyramid and zero values

[Shady]

Hi,

 I am trying to display a Pyramid chart with last point value set to zero, however no chart is appearing. Anyone knows if I am missing something or if this is a bug?

 A simplified testcase to reproduce is:

public static void main(String[] args) {
  Chart cc = new Chart();
  cc.setGallery(Gallery.PYRAMID);

  cc.getData().setSeries(1);
  cc.getData().setPoints(2);

  cc.getData().set(0, 0, 10);
  cc.getData().set(0, 1, 0); //If we change this value, the chart is displayed

  JFrame f = new JFrame();
  f.getContentPane().add(cc);
  f.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
  f.pack();
  f.setVisible(true);
  }

Note that the same chart displayed in Pie for example is visible.

Thanks,

Shady
