— Overall performance is poor.
— The app is not optimized for mobile devices.
— The first and the second graphs are broken, no lines are displayed. Appears only after tapping on them (the attached video).
— Scaling causes the graphs to hide, previews appear empty.
— The app is slow when scaling, scrolling and filtering the third graph.
— The graphs take the entire width of the page when viewed from desktop browsers.

When switching off a line on y_scaled chart, the related value labes keep displaying. ( I have the same problem in my work).

Overall the work has nice design and it's not fair people have put so many down-votes for it.

There is no restriction on tooltip position on mockups. From the provided design it is not clear where the pointer is.
Stacked: red values not visible

Not an issue. If value is too small to display, it shouldn't be displayed. It's a bad idea to draw fake data.

It seems you forgot pixel ratio multiplying for line width

X values are appearing lately when scrolling and messing up when scaling

2nd chart doesn’t hide y values on filter unchecking
