— Overall performance is above average.

— Graphs #3 and #5 are slow when filtering.
— Total is missing for the third graph.
— The box with the details about selected points on the graph does not reflect filtered data.
— Long tap doesn't work on some devices (LG Nexus 5X, Android 8.1.0)
— Filter buttons change their position when filtering on devices with small screens (e.g. iPhone 5S)

Chart with 2Y - y axis for unchecked data does is disappear

wrong date range

Percentage chart - tooltip shows data for unchecked filters

1. The tooltips don't hide
2. There is an excess animation when I long tap an only enabled line button
3. The tooltips show the disabled lines (the contest organizers noticed it in the 1st stage)
4. The buttons ignore the clicks sometimes
5. There is no "all" row in the stacked bar chart
6. The date scale shows translucent labels when there is no current transition

2Y chart: text doesn't disappear when toggle data filters

- no smooth animation between values
- button in plot #4
- no text animation
- "%" in last plot
- handles in minimap has no correct color in night mode
- buttons change their sizes and can even jump after click

The 'views' button displayed for single column chart. But that is a small issue.

In general the design looks nice, no dislike from me.

Charts doesn't render on left/right outside of container when trimmer not take full width of preview. Should render by design

Percentage: no need for "%" sign on Y axis

Night mode: vertical lines on trimmer should be white

On X axis days cut off

Line charts: "jumping" tooltip is hard to read (need to focus attention on each move)

Stacked, bars: wrong date range; missing bar for last day
