[Scilab-users] question non datafit

[Claus Futtrup]

Hi guys

Since I'm interested in the topic, I decided to look up the link 
(https://help.scilab.org/datafit) on my phone.

I was unable to see the majority of the graphs on the right and I was 
unable to zoom out.

I am able to 'replicate' it on the PC by narrowing the browser window, 
by which the pictures disappear to the right, and there's no scroll bar 
at the bottom.

I there any chance we could make the help pages phone-friendly?

Best regards,
Claus

I will try to update the index to improve that, a related bug is #12746. See https://bugzilla.scilab.org/show_bug.cgi?id=12746 for more information and discussion on that topic, do not hesitate to contribute if you have some SEO knowledge.
