Scatter plots are generally a nice tool to represent data, especially ones where we’d like to show a pattern of some kind. But what happens when we have a sub-pattern of data which we need to plot to understand the pattern in the scatterplot?
Let’s take an example here. This is how the data looks -
| Name | X – Axis | Y – Axis |
| Region1 | 3% | 17% |
| Region1 | 4% | 34% |
| Region1 | 3% | 14% |
| Region1 | 3% | 37% |
| Region1 | 4% | 28% |
| Region2 | 6% | 23% |
| Region2 | 5% | 30% |
| Region2 | 7% | 33% |
| Region2 | 6% | 25% |
| Region2 | 6% | 30% |
| Region3 | 7% | 50% |
| Region3 | 7% | 70% |
| Region3 | 6% | 59% |
| Region3 | 7% | 48% |
| Region3 | 8% | 59% |
and the scatterplot like this…
But we’ve got more information that could be plotted, only it’s not directly possible in Excel. The regions are a second level of data that could aid us in plotting and visualizing the data, maybe there some kind of pattern within the grouping that we’re not able to see currently from this chart!
Take a look at how this might look -
And what a difference it seems to make on what we can infer from the chart!
Wouldn’t it be great if we could do this instantly? Well, excel doesn’t seem to be supporting such a feature yet directly from the menus, but I guess we’ve always got the folks who just can’t keep it quiet when it comes to tweaking!!
Here’s a nice link that shows how this can be done!

As for me, I’ve got my own piece of code, not the most robust & efficient one, but definitely works! I’ll probably put that up sometime soon…
Enjoy the excel experience…
