[Matplotlib-users] size of the picture

[Julian]

Hi Vincent,

To get to know the width in LaTeX you can use the commands
```LaTeX
\showthe\textwidth
```
or
```LaTeX
\showthe\columnwidth
```
which show you the value you then divide by 72 to get the value you want 
to take for the width in Adrien's answer.

Best regards,

Julian
