ZingChart: Dynamically Set Bar Color Based on Previous Node Value
You can use our dataparse() method to dynamically determine color value of bars at parse time. That event is fired when the data is ready to be parsed by ZingChart. So I loop through and add color based on the previous value dynamically. I left the first bar a neutral color because there is no previous value to compare it to.
