I have a protocol establishing a bar chart for multiple data series. I tried to be generic but I realized that the bar chart component (if you use commas to separate y values) may not format the different bars with different colours unless each x,y pair is entered as a different data series using the data series 1,2,3 parameters.

What if I have 4 or more data series? How can I still use one single bar chart to view the different data series?
