Display Info When You Hover To A Data Point In Matplotlib (Source Code In Description)

This is one of the most requested topics so I thought I would finally make a video showing how to implement the feature when you hover your mouse on top of a data point a data label will automatically pop up.

There is one problem: The hover-event shows the x-value twice. It shows (x, x) and not (x, y). It has to be like this:
text_label = '({0:.2f}, {1:.2f})'.format(data_point_location[0], data_point_location[1])

[@jiejenn]

I didn't notice that. Good call!

[@vishwanathkadalagi2336]

it still ends up showing (x,x)?

[@ClaudioPisa-c5z]

Do you think is possible to do so with a simple graph and not with a scatter plot ?

[@jiejenn]

Definitely. You can do it with any type of graphs.

[@star-wp7os]

hi, thanks for your video.
how can i apply this code at 3D scatter plot?
i tried it but ....
i made scatter like this " scatter(x,y,z) " and ran " scatter.get_offsets() ".
result was different that i think
how can i get (x,y,z) data?

[@jiejenn]

I don't have much experience working with 3d graphs, I would suggest you post your question on Stack Overflow.

Hi, I tried rer-running the code, it is throwing this error:
Traceback (most recent call last):
File "./prog.py", line 23, in
TypeError: annotate() missing 1 required positional argument: 's'

[@jiejenn]

Annotate function is missing a parameter value.

@@jiejenn how do i solve this. It is not showing any error when you did yours. Thanks

[@jiejenn]

I charge a $7 fee for troubleshooting. Let me know if you still need my assistance.

[@taiwoosunrinde3927]

@@jiejenn for the code you wrote or the one I am trying to make work , using your approach. Just need clarification on what I will be getting

[@jiejenn]

@@taiwoosunrinde3927 it is almost impossible to troubleshoot by looking at an error description without knowing what the code looks like. That's what I'm trying to say.

[@rcsmit]

Why not using plotly? They do it by default

[@jiejenn]

I prefer matplotlib.

[@jackingo]

I'm unable to do this in google colab the hover doesn't appear in it

[@prxshetty]

Did you get the solution for this??? I have been stuck at the same problem too. 🥲🥲

[@SpectacularAustin]

Can you make video on how to delete ALL videos on a TH-cam channel using YT API?

[@jiejenn]

I will look into it.

[@philtoa334]

Very good thx.
