plot number of items that lie outside the euler diagram
Hello,
thank you so much for the nice Euler diagram implementation in R. I only have one question for you. I was looking at the plot.euler
page and I wasn't able to find a way to plot a number outside the circles representing the items that are "outside" the euler diagrams and not belong to those grouping variables. Is there a way to do it?
Thanks a lot,
Gian
Unfortunately there is no such argument, though I am not convinced there should be. I would argue that it's the intersections that are of interest in a Euler diagram and not the complement to those intersections. However, if you think otherwise I'm sure I could be persuaded.
In any case, it is very easy to fix this yourself. You could do one of the following two:
library(eulerr)
library(lattice)
library(latticeExtra)
plot(euler(c(A = 25, B = 25))) +
layer(panel.key("n = 10", points = FALSE))
plot(euler(c(A = 25, B = 25, "NOT A, NOT C" = 10)))
Hello @jolars thanks a lot, it looks like it worked :+1:
plot(euler(c("A" = 39, "B" = 202, "A&B"=46), labels = c("A","B")), fill_opacity = , fill=c("#33A02C","#1F78B4"), lty=0, fontface = 0, counts=TRUE, main="(A)") + layer(panel.key("n = 16", points = FALSE))
I have given this thought and I do not think that I will support this since a principal feature of the diagrams is that the shapes are area-proportional and this is already a possibility by specifying a set that contains the other sets, like this (using ellipses):
plot(euler(c(C = 16, "A&C" = 39, "B&C" = 202, "A&B&C"=46), shape = "ellipse"))
Not perfect, but at least it maintains area-proportionality.
First of all thanks for this great package. I am reopening the issue because I have a related question. Euler diagrams can be used to display the percentage of of explained variance due to various components. This is then a share of the total variance. Often the total is drawn as a box around the euler diagram and the size of the circles are scaled proportional to the proportions explained. Can this be achieved using eulerr?
Unfortunately not @mkschneider. This would be difficult to achieve while still maintaining proportionality of the diagrams. I am open to pull requests addressing the issue but will not work on it myself. I'll reopen the issue, however.
