Diagram should also show price per unit

[trapicki]

Currently, when selecting "Mengenpreis" (price per unit), and showing a diagram for certain products, the diagram still shows the price per item.

• Milka Alpenmilch, with interresting prices for 100g, 270g and packs of 500g
• Rauch Eistee Pfirsich 330ml, 500ml, 1l, 1.5l, 2l.

Would be very helpfull for proper comparison.
