Question about Check Box / Multi Select

Question about Check Box / Multi Select

I have a checkbox with, for sake of example, the following information:

Apple
Pear
Orange

And for each person, I want to track which fruit they like... so:

Johnny: Apple
Bobby: Apple, Orange
Susie: Apple, Pear

... and then I'm trying to import this data into Zoho's DB's to produce a report (no problem doing this), but then show a pie chart of how many persons like Apples, Oranges, and Pears...

Therefore with this data, I would have a pie chart of 3 counts for Apple, 1 for Orange, and 1 for Pear.

What is happening is that the pie chart is considering:

Apple
Apple, Orange
Apple, Pear

... all as one long string, or value. So we then have the pie chart split into 3 equal areas, being "Apple", "Apple, Orange", and "Apple, Pear". Please help!
