I want to show points across two groups. However, for both groups, there are some points which are far away from most of the other points within each group, shown below. Any suggestions for this situation? Thank you.
If you want to see the distribution of the data that is hidden in the bottom portion, you can add a histogram or probability plot, or even a violin plot. Each will show the distribution of the data more clearly than this boxplot does, and you can still see the true value directly. You can also add some jitter to the boxplot to see more of the overlapping points displayed.
If the values are greater than 0, you can apply the logarithm to
Value and you should be able to compare the distributions much more. Another thing you can do is cropping at some value (let's say
Value = 10) but you are going to lose some information.
If your values are not greater than 0 but have a lower bound (let's say
-t), you can apply the transform
log(x + t), and the logarithm won't explode.
