I have a custom data source implemented which returns rows that contain multiple values:

dataset1: value1
dataset2: value2
dataset3: value1, value2
dataset4: value2, value3

At the moment when I use a pie chart for example it counts "value1"; "value2"; "value1, value2" and "value2, value3" because it does not know to split the values.

So how can I use the pie chart to count "value1", "value2", "value3" and "value4" seperatly?

I assume those are strings? Anyway, the short answer is that you can't - charts and graphs are based on singleton value items. You'll need to transform your data to get the numbers you want into your charts.
