{tastypie} 0.1.0 here!{tastypie} crew and get a free tasty_tshirt? Find out the details here.You only need to type “why pie charts are bad” on Google to find thousands of articles full of (very valid) reasons why this type of chart should not be used.
However, my mother, a high school teacher of Latin and Italian Literature, swears she understands more from something like this:
than from something like this:
|
InYourOpinion |

|
My mum |
60 |
0.2 |

90 |
0.3 |
|
Strange? |
150 |
0.5 |
Now, I love my mum, and I want her to be happy. Maybe there are other people in the world with this particular problem, so, why not help?
Due to the little use because of the already mentioned reasons, making pie (and related) charts in R is not straightforward, so it is necessary to have functions to simplify things.
In this R package there are useful functions for making tasty pies exploiting some ggplot2 features.

Using pie_bake() you just have to choose a template and if you want the proportions to be displayed in the plot or not (if you want, you can also set a title and a group name):
example <- data.frame(
c("a. Is", "b. Not", "c. The", "d. Only", "e. One"),
c(2.9, 6.9, 4.20, 13.12, 6.66)
)
pie_bake(data = example, template = "basic4", perc = TRUE,
title = "Perhaps", group_name = "She")
Or, if you want something more extravagant (but probably less understandable), choose a template and try pie_bake_pro():
Or, if you are interested in a circular packing chart, you can easily do it with the bubble_blow function:
exblow <- data.frame(
LETTERS[1:8],
c(33, 24, 54, 12, 43, 88, 66, 78)
)
bubble_blow(exblow, template = "bub2", perc = "below", title = "Easy bubbles:")
Not sure which template to choose? Run pie_discover() to find out a random combination of templates, number of groups and features and get an idea of the many available plots:
Want to display an example of a particular template with particular features? Try pie_templates():
