Inspired by the Dubliners (Wikipedia: http://en.wikipedia.org/wiki/The_Dubliners) I created a graph that reflects the years when the different members were part of the group.
It is all a bit complex. In the upper table part I use the number 1 to indicate whether a person was a member. Using conditional formatting I converted the 1 into just a green ball.
Below we see the graph. This graph looks like a clustered bar, but is actually a stacked column. Per year a stack of 1's is represented. This alone would not be enough, of course.
In the graph itself I therefore added ranges that contradict the ones of the members. If Ronnie Drew was no member in a specific year, the contradicting range would contain a 1 etc. Those contradicting ranges are based on names with formula's like:
In thee graph the added ranges then look like this:
The color of the name based contradicting ranges I put to white in the graph. So you can not directly see them. In short, every stacked column consists of the same total of white and colored blocks.
