Juice Analytics, one of my favorite visualization blogs discussed about creating bubble charts that can depict search term competition among major travel sites in bubble bubble toil and trouble.
Chris, who wrote the article said,
The first tool we tried, simply on principle, was Excel 2003. As expected, making a … quality bubble chart in Excel 2003 is a hard problem. Here’s a draft of how far I got before giving in to label fatigue.
The bubbles themselves aren’t tough, but getting the labels right is hard. I’d love to see a solution, so if any reader wants to tackle it eternal fame can be yours.
Well, not that I would get eternal fame, but I wanted to give it a try, just for fun. Ever since I saw the NY Times Bubble chart on “how many times each political candidate used certain terms”, I have been itching to recreate it somewhere.
Here is the version I could create in Excel 2007
(larger version of the travel site search terms visualization)
How I made this?
- I started with travel patterns data Chris shared
- Then I used Excel formulas OFFSET() and ROW() and COLUMN() to rearrange the data in a tabular format (the original format is a matrix)
- Then I sorted the table on bubble size
- Now I made a bubble chart with 3 data series, one with bubble sizes >50%, one with 25-50% and the rest
- I formatted each series and added labels to the first two series
- Finally made some alignment and bingo

How would you have designed the chart ?

Noooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooo!!
Whyyyyyyyy?
The idea is to tell how to make a bubble chart. I got an e-mail from a reader recently asking how the scatter bubble is made. So I thought a 15 second tutorial would be a good idea to show this.
Did that email go "Dear Chandoo, I know that you scorn bubble charts, but if I don't do one in Excel for my boss then he'll fire my sorry ass, and my children will have to be sold for medical experiments in order for me to be able to afford the upgrade path to Excel 2010"?
If so, fair enough...it's all in the greater good 😉
Chandoo,
I am using excel 2003 and it is not working. The x axis is not the one that I enter in x axis column. Please help! Thanks.
Sorry, after few attempts, I managed to get the right result. I shouldn't select the title (header) of the table and select only the data to produce the right bubble chart.
What's wrong with bubble charts? Is there a better method for displaying scatter plots with lots of overlapping data points? Don't tell me you'd rather jitter!
@Sanwijay: Cool.
@Precious Roy: There is nothing wrong with bubble charts. Infact, it is the only way to show 3 dimensional data (x,y and sizes) without confusing your audience. Jeff is worried that people might misuse the chart. As with any chart, bubbles also have a place and time for using them.
I recommend using bubble charts to show relative performance various products in several regions and similar situations.
Also, human eye is notorious in wrongly estimating the bubble sizes (as we have to measure areas). See http://chandoo.org/wp/2009/07/28/charting-lessons-from-optical-illusions/
We can partially improve bubble charts by adding data labels, but if you have too many bubbles, the labels will clutter the chart and make it look busy.
I can't seem to find a way to plot more than ten bubbles on a chart and need to know how to add more
@KW.. why would such a thing happen. I am sure you can add more bubbles that that. Can you tell us exactly what you are doing...
Example table:
A B C (size)
Me: 25 30 15%
Him: 30 22 11%
Her: 12 30 20%
I am trying to make a bubble chart where the Y axis is A, the X axis is B, and the size of the bubble is C. There should be only 3 bubbles. I keep ending up with six (with the labels being only "Me" and "Her"). My goal is to have three bubbles, one representing each person. Clearly I am doing something wrong. Can you help explain...?
Hi,
I wanted to add data labels to the bubbles. Each bubble represents a different company name. Excel allows me to add the size, legend, x axis values and y axis values. How do I add instead- Company A, B, C, D for the bubbles?
youon you have to choice every data for every company..
ex:create bubble for A company,after that click right> add data label> adjust data labels :format data labels and choose : series name.
i hop u will succeed .
[...] we create a bubble chart with 2 bubbles. 1 for the actual mustache & 1 for target [...]
If we want bubble size to be controlled by one column, but the bubble labels to be controlled by another column, how can this be achieved?
many thanks!!!!
