New feature: add additional info to the hover over text

[yb2125]

First, thanks for developing and maintaining this great package.

Is it possible to add a new feature allowing more information to be added to the hover-over text? For example, in addition to the numeric value, display information for the value from another column of the data set for each data point.

Thanks!

There's already a solution to this on Stackoverflow
