I'm working on an application that display a large amount of data (EEG and MEG data to be specific), coming from different files.
The image below show an example of what I can have if I load datas coming from 3 different files:
As you can see, it can be a little overcrowded. Even with color, it can be difficult to differentiate them. Each graph comes from a specific file and have a specific label (as seen on the left side of the picture).
I want to add a new feature, but I don't know how to do it, if it's even possible.
When the mouse goes over a graph, I want a small square to appear (near the mouse if possible) with various information about the graph (like it's file and it's name).
Any idea on how to achieve this?
