And completely missing, the old reliable pie chart. Used when showing attributes (percentage, counts, etc) of a whole.
And then there's the scatterplot. Very useful in regression models for best fit.
Charts and plots are tools. To limit yourself to just three is using a screwdriver for a hammer, or C# for any programming task.
Understand the available tools and use the right one for the job at hand.
- danso 14y agoPie charts are controversial, as the human eye is easily misled by them. A discussion on Edward Tufte's site: http://www.edwardtufte.com/bboard/q-and-a-fetch-msg?msg_id=00018S http://www.edwardtufte.com/bboard/q-and-a-fetch-msg?msg_id=0...
- defrost 14y ago> the old reliable pie chart. ? Weird. In the past 35 years working in numerical analysis of multitudes of data sources from toilet flushes in a city of a million people to stock movements to multichannel radiometrics, to cloud data from LIDAR, to cot death incidences, etc. I've never once used a pie chart (or, in fact, worked with anyone that's used them). I understand they are popular when lying with statistics and in power point displays to non technical suits, but they have pretty limited use in understanding data or presenting layered attributes. Scatter plots are somewhat useful, when combined with a means of indicating densities, such as heatmapping; box and whisker plots that show central densities, means, medians and extents of ranges are useful. But Pie Charts? Professionally they're the joke setting in Excel . . .
