— Overall poor performance.
— The graphs are blurry.
— Y-scale always starts from zero on the first graph. 
— The app is slow when scaling and scrolling graphs #2, #3 and #5, also sloppy when filtering the third and the fifth graphs.
— Total value is missing for graph #3, long tap not implemented.

undefined NaN in tooltip text on all graphs
(check screenshot attached)

blurry labels, tooltip is displayed behind the screen, no support for landscape mode and long tap

The scrubber borders must be outside

Line charts: no animation when toggle data filters

Line chart 1Y: not start from min value

Stacked: no "All" row

"The Y-scale on line graphs should start with the lowest visible value (Screenshot 4)." - not implemented

There is no "All" field at the bottom of the tooltip

Another small issue is that the text of switched off buttons is not centered inside a button. But that doesn't effect any functionality and is very easy to fix. Probably should be ignored.

Not a bad work at all! I wonder why people have put so many dislikes for it. No dislike from me.

Stacked, bars: wrong select on hover most right bar

Chart width is same as preview when not whole preview selected. Chart should be wider
