Is there a library for labeling scatter plot while avoiding label overlaps?
显示 更早的评论
I would like to plot many data points in a scatter plot and some data points are located very close together. Is there a library for smart label placement so that the label overlap will be minimized?
I found a package for R: https://cran.r-project.org/web/packages/ggrepel/vignettes/ggrepel.html which seems to provide this functionality. Is there a similar library for MATLAB?

This kind of labelling has always been cumbersome in Matlab. Nevertheless, it is astonishing that this important functionality is included in freeware like R but not in sth as expensive as Matlab. I just had to create a scatter plot of a cyclone track through the SW Indian Ocean and needed to add time & date labels to each cyclone position. In R it looks rather nice, in Matlab it is a disaster.
One workaround may be
gtextm('String')
which places the labels manually, but if you have like 30 of them this isn't much fun.

I am not aware of anything provided by MathWorks. You might look through this post, as well as looking into this file exchange function.

Labelpoints does not prevent the overlap of labels which is what the question was about.
