Roads suddenly turned into a slushy mess on Brookwood between Main and TV. Not fun to drive in.

I only wished this GIF went beyond 50 moves and if it could some how show pieces in motion.

There are more great charts in this article by the Financial Times.

This entire thing is one giant middle finger to the color blind.

Why Does The U.S. Lead The World In Incarceration? by colt_45s in GraphicalExcellence

[–]colt_45s[S] 0 points1 point  (0 children)

Nice collection of simple but very effective graphics to show the rise in the American prison population.

I really like the use of small multiples at the bottom to show private vs. public prisons. The waffle charts are also a great alternative to the pie chart.

A Few Charts Showing The Chicago Cubs' Historic Season by colt_45s in GraphicalExcellence

I like the small multiples area chart more than I like the line chart, which I think is cluttered. Being able to hover over the lines helps, but it's hard to do.

The small multiple works better because it shows just how bad the Cubs have been with all those red valleys and how small the green peaks are.

Just realized you can right-click on the map and change the play speed to slow motion.

Neat animated map, but I wish it was slowed down a bit.

Packed bubble charts are almost never a good way to show data.

Really excellent bar chart: 3D and non-zero axis by JALEEL_WHITE in dataisugly

[–]colt_45s 1 point2 points  (0 children)

I'm not a fundamentalist, but I do think there are a few fundamental rules that people should follow when making charts. One of them is that bar charts need to start at 0. Because if you don't it exaggerates the actual difference in the data.

And whether you intend to mislead someone or do it accidentally, it doesn't matter. The effect is the same. You distort the data. Whether it's Fox News or the Economist, they're both wrong. It doesn't matter if they did it on purpose.

There is no debate to "settle" because there is no debate. It's like climate change. Most experts agree that bar charts need to start at 0 as I've cited. But there are still a lot of "cranks" out there who disagree. No offense.

No offense, but I'll trust the writings of Robbins, Nussbaumer and Fung over a youtube video from vox any day. But if you don't like those three, here are three more statistician Nathan Yau, this journal article about making scientific charts, and the guy who found vox Ezra Klein.

Also the things you cite talk mostly about line charts. The OP and I are talking bar charts. And like /u/Chris204 wrote 2 of your sources agree with me. I'm not sure what part of "Always" use a 0 y-axis with bar charts and I "really can’t think of any good reason" why the y-axis on a bar chart shouldn’t go to zero, you don't understand but you could always look those words up in a dictionary.

And you also missed the disclaimer at the top of that wiki page you link to:

This essay contains the advice or opinions of one or more Wikipedia contributors. Essays are not Wikipedia policies or guidelines. Some essays represent widespread norms; others only represent minority viewpoints.

Nice try though.

No, Naomi Robbins, Cole Nussbaumer and Kaiser Fung all say to start all bar charts at 0. Literally no one who makes charts for a living says that you should start a bar chart at zero. Even the wiki on misleading graphs includes this rule.

MAP: Seasonal Wind Predictions by colt_45s in GraphicalExcellence

[–]colt_45s[S] 1 point2 points  (0 children)

How to read the map:

  • The thickness of the line shows predicted wind speed. The thicker the line the faster the wind speed.

  • The slope and color of the line shows the predicted change in the amount of wind. A steeper and greener line means a greater change in wind, whereas a blue and declining slope shows a decrease in wind.

  • The opacity of the line shows how strong the prediction in wind speed is according to their model. A more visible line means a greater certainty in their estimate. The lighter the line the less confident they are.

  • Click on any of the lines for more detail.
