- john_horton 14y agoAgree that 3D graphs are terrible, but it's a canard that y-axes always need to start at 0 and that doing anything else is somehow misleading. On this point, see http://krugman.blogs.nytimes.com/2011/09/14/axes-of-evil/ http://krugman.blogs.nytimes.com/2011/09/14/axes-of-evil/
- aaronjg 14y agoY-axis need to start at zero when the data being presented is a bar graph and the bar is filled in. If it is a scatter plot with points being plotted, then it's generally not misleading to shift the axis.
- john_horton 14y agoI don't disagree with that - a bar chart that doesn't start at zero can be misleading. But for what he was trying to do---compare means---it would have been a perfectly fine choice to do a lineplot/very thin bar plot and start the y-axes somewhere other than zero if he included error bars and clearly labeled things. http://www.edwardtufte.com/bboard/q-and-a-fetch-msg?msg_id=00003q http://www.edwardtufte.com/bboard/q-and-a-fetch-msg?msg_id=0...
