I have created a bar graph that shows responses to a survey. The survey is
anonymous so the graph does not reveal the ID of repondants against the
individual bars on the graph. However, when I print the graph in a
customized survey report, I want the graph to show each respondant how they
performed against the rest of the group by changing the colour of their
individual data point. I can manually do this by simply selecting and
changing the colour of a specific data point. Is there a way to do this
dynamically?
