Google Chart API Revisited. Marty does some more digging. # 7th December 2007, 11:59 pm

Unfortunately, I was shocked, horrified and moderately surprised to see that nowhere is there any mention of how to encode negative numbers. Google, I appreciate you trying to help, and I understand that this grew out of needs for Google Finance, where stock prices can never dip below zero. But there’s really not that much data out there in the real world that always exists solely above the origin.
