Yesterday I read about interaction plots on junk charts where he points out the merits of an interaction plot. Interaction plots show interaction effects between 2 factors. For eg. you can show how your product sales have changed between year 1 and year 2 using an interaction plot like below:

As you can see, interaction plot is a simple line chart with several series. You can easily make this in Excel. Here is a simplified tutorial to help you get started.
Step 1: Select the data and insert a line chart
This is simple, just insert a line chart from the data.
Step 2: Go to the line chart “data” and change rows to columns
You require this step only if your data is oriented differently.

Step 3: Format the interaction chart
Since excel colors each line series differently, you need to change the colors, add labels, adjust the label source (from data to series) and then format grid lines etc.
That is all, your interaction plot is ready to go.

Points to consider when you are making interaction plots,
- Interaction plots can be too messy if you have a lot of series. Generally they loose the appeal after 6-7 series of data.
- Chart formatting with more series of data can be a pain too. Use F4 key if you are found repeating same steps.
- Make sure you don’t color individual series differently. You can use same color and label instead. It looks a lot better that way.
- In cases like last year vs. this year or budget vs. actual, you can even use clustered bars. See more examples on budget vs. actual charts for inspiration.
What is your opinion about interaction plots?
I think they are good for small data samples. I have personally not used them, but I like the idea and will use them when there is an an opportunity. What about you? Have you used them in any professional setting? How did your audience feel about the chart? Tell us using the comments.
