Graphics, Figures & Tables ⇒ Multiple subfigures not appearing on the same line

[Lumy]

The subfigures do not appear on the same line. The figures must be the same dimension.

Thank you for your help!

The code is :

Package subcaption uses minipages for the subfigures. Knowing that, we know that we can set the optional argument for alignment. In this case we align all the subfigures on the top ([t]).
