— Overall performance is poor.
— The first graph jitters when scaling and scrolling.
— Graphs #2, #3 and #4 are slow when scaling and scrolling. Graphs #3 and #5 are slow when filtering.
— The graphs take the entire width of the page when viewed from desktop browsers.

So strange bug with scaling of line charts on buttons switch on/off. At some point it stops scaling correctly.

But in general not a bad work. No dislike from me.

Step size changes only when the boundary points go beyond the first two and last regions. This is intentional to avoid too frequent minor transformations.

Line chart 2Y: doesn't reach bottom

I see that everything is fine on the screenshot

Bars: red data not visible. Preview: doesn't reach top
MBP 2018 15, Chrome, Mojave
Witty Owl Apr 25, 2019 at 07:45
this is a correct display of data, the indent on the preview is made for convenience
Crazy Pug Apr 24, 2019 at 22:54
Bars: no need for data filter for only 1 type of data

Witty Owl Apr 25, 2019 at 07:47
you are right, this is not in the design, but it is logical to display it in my implementation because it is possible to disable all datasets
Crazy Pug Apr 24, 2019 at 22:56
Data filters: when toggle - width of button changes and hence all buttons move - bad UX

duplicate, already fixed
Crazy Pug Apr 24, 2019 at 22:58
Stacked, bars: when select not whole preview - position of most left/right bars changes and hence renders outside of main chart

Witty Owl Apr 25, 2019 at 07:53
all bars are the same width and centered relative to the date
