+ Here is a list of all types you may set:
+
+ type
+ ----
+ 'bar' 1 => Vertical bars (default)
+ 'horizontalBar' 2 => Horizontal bars
+ 'dot' 3 => Dots
+ 'line' 4 => Lines - Series Type Fill => Area
+ 'pie' 5 => Pie
+ 'donut' 6 => Donut
+ 'halfDonut' 7 => Half Donut
+ 'spline' 8 => Splines - Series Type fill => Area
+ 'table' 9 => Simple HTML table
+
+ labels[0] => Name of the first parameter in Axis X
+ labels[1] => Name of the second parameter in Axis X
+ ... (etc)
+
+ series[0]['data'][0] => Value relative for "labels[0]"
+ series[0]['data'][1] => Value relative for "labels[1]"
+ ... (etc)
+
+ series[1]['data'][0] => Value relative for "labels[0]"
+ series[1]['data'][1] => Value relative for "labels[1]"
+ ... (etc)
+
+ NOTE: When using 'pie', 'donut' and 'halfDonut' only the first data set is used.
+
+ That's all! Hope you make a good use of it!
+ It would be nice to receive feedback from others users. All comments are welcome!
