There should be a class or custom class applied to your page, layout or container etc. which will have some media queries. Find that class name and search for it in your SASS / CSS files to check and update the styles. You can also find what class / styles are applied by inspecting elements in google chrome, once you find them you can make changes to your SASS / CSS accordingly. If there is no class found then you can create your own with media queries styles and apply that to your element. It is also worth checking _variable.scss and custom-variables.scss files to find default media queries breakpoints.
Hope this helps!
I think its your graph.
delete it, and see if your page goes responsive.
(I think the graphs have styling that dont work well with responsiveness)
