Pie Chart can't have more than 7 data

[mpalencia]

Try to use 10 elements of an array on a pie chart. It will display only 7.

Maybe @pvanagtmaal can help here, he was the one developing the Pie chart.

Closing this, tested it will work on several data, more than 7, but will not work if a data is the same with other values.
