— Overall performance is average.

— Graphs #3, #4 #5 are slow when scrolling and filtering.
— Y-scale starts from zero (the first graph).
— 'Total' values is missing for graph #3, percentage is missing for graph #5. Long tap is not implemented.
— Bonus goal is implemented, however data info on the pie chart is missing.

Hey, thanks for the review! Those yellow lines was a hard decision. However, it's not technically possible to use the same grid lines for both charts, because Y-axes have two essential features:

1. They have fixed scale levels so we can always have lovely labels like "50" or "250", but never "49" or "252".

2. The axes have stretching height and flexible rows amount, which allows making smooth transitions between different levels and also avoiding redundant label updates, which exists in many other apps.

Even if we'd find a way to make both Y-axes "fit" at some point by both scale step and row height, we would then face issues with animation, when chart lines go into opposite directions. It will cause one axis to "grow up" and the other to "shrink down", so at some point, the labels and the grid lines will also go the opposite way.

Something is wrong with y-axis labels (horizontal lines) for the zoommed mode of the first chart.

Inconsistent state of chips (a.k.a. selectors, buttons) between the standard and zoommed modes. Either the buttons should get checked, or the lines should be hidden - in any way the shown lines should correspond to the checked buttons.

Thank you for the review, nice points! I wish I had a little more time to test it all out.

Unable to select time range by dragging in the preview area (outside of the current window).

Hey! Not sure what you mean "outside of the current window"?

Not working in IE11 (ES5) and no bonus goals. Animated changes in throttle function queued and you can skip the intermediate steps in future. But I like for the other smooth animations and implement text change. Voted.

Hey! Thanks for the review. Yes, only Edge is supported. I do have bonus goals, or what do you mean, any specific browser? I do also have throttling and debouncing, where do you think it’s not efficient? Thanks for your vote too!
