They are also more flexible: you can show percentages as you did, or you could compare the raw numbers instead, which would be impossible in multiple pies.<br /><br />In the right setting (the small blue wedge in your last chart, he he), pie charts are a reasonable choice. I guess I'm pretty vocal about them because they are used in the wrong setting so much of the time.<br /><br />P.S. You got out of Beantown just in time.

I have a different suggestion for...Happy New Year!<br /><br />I have a different suggestion for comparing Morris and Blyleven: a Dot Plot. I compared dot plots to tornado charts (a name for the bidirectional bar chart you used) in http://peltiertech.com/WordPress/tornado-charts-and-dot-plots/.<br /><br />Tornado charts have several shortcomings. You already noted that you can only compare two players, and that you had to omit negative values. More problematic is that the bars go in opposite directions, so direct comparisons are cognitively very difficult.<br /><br />I've posted a dot plot comparing Morris and Blyleven at http://peltiertech.com/images/2011-01/blyleven-morris-1.png. (I've neglected to label the chart other than the players' names.) Feel free to copy it to your site and paste it into this or any other post.<br /><br />The dot plot shows these two players clearly, and you could add more easily enough (making sure to stop before the chart is overly cluttered). You can actually see that Blyleven had eight seasons better than Morris' best. You'd need a ruler to determine that with the tornado chart.Jon Peltierhttps://www.blogger.com/profile/05234895820595509962noreply@blogger.comtag:blogger.com,1999:blog-4257932056731228876.post-9782169241711798652011-01-16T17:24:24.833-08:002011-01-16T17:24:24.833-08:00Good post.

A pie chart is okay for a qualitative comparison, but not a more detailed quantitative comparison. And you've created the only thing worse than a pie chart, according to Edward Tufte: several of them. In your pies, I can tell that Aaron had about the same pctg of K as BB, and Ruth and Bonds had about the same pctg of K. If you'd provided a bar chart, with one category per player, one series per quantity compared, and the value axis in percent, we could not only see the data qualitatively, we could actually compare the values with some precision.<br /><br />Logging into Beyond the Box Score with my facebook account failed, so I couldn't reply there. I also wanted to take issue with the comment that truncating a bar chart is okay (it isn't, our perception of the bar lengths overrules the axis labels) and with the comment claiming that pies are good for any number of categories (his example pies have so much decoration that they are nearly useless).Jon Peltierhttps://www.blogger.com/profile/05234895820595509962noreply@blogger.comtag:blogger.com,1999:blog-4257932056731228876.post-7170631407722834492011-01-07T06:59:35.942-08:002011-01-07T06:59:35.942-08:00You're right -- Axis labels are very important...You're right -- Axis labels are very important if they aren't immediately obvious.

One suggestion I think is the most important is to label your axes and be sure to tell me what I'm looking at. I've seen some awesome visualizations where I don't know what it is showing me.<br /><br />The bar/line graphs are straight forward by your title(s) above, so those aren't a huge worry. But I always find it a useful exercise to assume the reader knows absolutely nothing about the picture I'm showing them, other than what I explicitly say.<br /><br />Thanks for the post. These are always instructive.

I'd need all 10 ways that you can get to a 3-2 count, the 6 ways to get to a 2-2 count, etc. And I'm not exactly sure what format would work the best. If you want to take a shot at it together, let me know, and I'll be happy to think it through with you.
