All completed.

Not sure about how many systems have GTK4 installed vs GTK3.
@stsdc : do you think switching to GTK4 is something good for your monitor application ? Or do you think that we should have 2 different builds / flavor for GTK3 & 4 ?

P.S. thanks @taozuhong for your PR :)

Right now Monitor is still on GTK3, I'm waiting elementary os to switch to newer base with GTK4 support.
If possible, I would like to have one last GTK3 release of live-chart.
I 'd like to see live-chart moving forward, therefore, I do not think that supporting two flavors will be efficient.

Fine ! @taozuhong I'll merge this PR when @stdc monitor app will be ready to move on GTK4.

Honor to get it.

@lcallarec I'm ready to move to GTK4. This can be merged!

Merged into master. Thanks @taozuhong for your contribution, and @stsdc for your patience :)
I'm preparing a proper new release for live-chart.

Thank you! ✨👍

Great news, seems that version 2.x will coming soon.

Livechart will landed on macOS soon.
