Slow overall.

— Delay on start.
— The design does not fully comply with the guidelines.
—Vertical scrolling is sloppy.
— The app is slow when scrolling, scaling and filtering.

After when I rendered a bar chart, I decided to save this side effect because it's visualize split bars.
Pie chart timeline (navigator) doesn't allow selecting more than 1 day. The navigation is not in 1-day steps. It is possible to place the timeline magnifier in between days.

Incorrect view of turned off buttons.

I was targeting to implement bonus goals and didn't apply a new design.
Hard to zoom to pc - tooltip runs away from mouse

To switch the zoom you need to click on the pop-up, to fix the pop-up in one place during mouse events - click on the chart.
Incorrect view of mini map.
Desktop, macOS 10.13.6, Google Chrome 73.0.3683.8
Space between bars, Y axis values are not converted to M notation as 5M, 10M
In zoomed mode I cant change zoom value itself

I did it on purpose to show only 1 day in the header
Checkboxes bug when dragging preview on Edge

Can't reproduce.
Edge freeze when expand x-range on Chart 5
Flashing text when the application starts
Incorrect 2Y-axis chart implementation: second line should be scaled to full extent of the drawing area

I did this on purpose to show that the second line is an order of magnitude smaller than the first.

It can be interesting for you, but I partially agree with you )
Pie chart tooltips don't display values. Probably a small issue - they display percents instead.
Chrome 73
The order of the elements of the stacked percentage chart seem upside down - starting from the lowest values at the bottom.
But that is definitely non-critical, as it doesn't break any functionality
Chrome 73
The app is non-responsive (no window resize or orientation change support)
This can probably be ignored. It doesn't effect core functionality, just usability.
Chrome 73
Minor styling issue: the values in tootlips are formatted not like in the requirements (requirements have full value in comma separated format).
Chrome 73
>I did this on purpose to show that the second line is an order of magnitude smaller than the first.

That's an interesting explanation and design decision found not only in your application, I wonder why is that, because I find that design guidelines are pretty specific on that part, no offence.
I like those animations. Pretty close to task.
Tooltip dancing in IE11, but good zoom and pie animations. Voted
Windows 8/IE11
The whole page STOPS RESPONDING after a chart is zoomed out
