Zing Chart Stacked Graph
You can access node values by both plot and node index. For example, (%node-value)(0)(4) would give you the value of the 5th node on the first plot.
Since a stacked bar graph is technically 2 plots, you could use the following tokens in your second (Open) plot:
"text":"%node-value:(%node-value)(0)"
A live example is below - run the snippet to see the chart.
