90% of you can see up to cell M26 & other findings [visualization]
Two weeks back I ran a poll asking you to tell me what is the last visible cell in your excel window. It was a casual poll. So I didnt expect a lot of responses. But, boy I was wrong! 295 of you have responded at last count. This is so much more than what I expected.
As I said, the purpose of this poll is to make a visualization out of the poll responses.
First let me show you the chart(s) I have prepared:
How to read this chart?
- The heat-map represents 221 rows & 89 columns worth of excel cells.
- Each cell is colored based on how much % of survey respondents could see it. The darker a cell is, more the people see it.
- The box plots at top and left show the distribution of visible columns & rows. For eg. the median columns visible is 19 and rows is 38.
- The grid lines show % of people who can see those cells progressively as indicated in the Key findings box.
- Source data: http://chandoo.org/wp/2010/10/29/last-visible-cell-poll/
- Chart inspiration: Browser Size by Google
What to do with this data?
If you publish excel files, you should fit as much as possible in to the range A1:M26.
How this chart is constructed?
- The heat-map is made with conditional formatting in Excel 2007. [video, tutorial, more..,]
- The Box plots are regular bar / column charts with extra series and a bit of formatting. Inspect the download file (link below) for details or get Jon’s box plot utility to make one.
- The legend is a regular column chart with gradient fill.
- The key findings is a text box with typed in text.
Key things to note about the data:
- Quite a few survey respondents mentioned more than one cell address in comments. I have considered only the first response.
- Many of you emailed me your cell addresses, but I did not consider that input as it was a tedious job going thru mails and extracting this information.
- I have removed one outlier where the cell address was something like A119. Rest all were fine.

What do you think of this chart?
I have considered several options for visualizing this data. Finally, I took the inspiration from Google’s browser size and settled for the one you are seeing above. What do you think about it?
