Slightly sloppy when scrolling the first two graphs with maximum time range. Y-scale always starts from 0. Decent speed overall+

Press the graph, double tap on "Zoom out" and it's crashed.

Bad pie chart animations. Look like simple morph.

1) reduce the time selector and move it to the left side
2) press the graph on the right side
3) wait until the right part of the time selector started to move to right
4) catch the right part of the time selector and move it to left
5) wait and release the graph and the time selector
6) it's buggy

Sometimes view with values is cut.

Charts dont keep their state and get reset on table scroll

wrong values range. starts from 0

Y label animation is wrong, goes from bottom even if bigger numbers.

1 Mask on bar charts blinks on hide
2 Unmasked area has borders
3 When it is about to leave the screen it recolors and blinks

Either range selection works incorrectly, or the date labels show wrong dates. We are zoomed into 6 Apr, and drag only left range selector part to the left. It then shows Apr 4 - Apr 5. But the right bound was not touched. It is hart to tell what exactly is wrong, because there is no way to see numbers in pie chart.

Respecive axes dont hide when applying filters on the double axis chart

When transitioning you can briefly see the circle point of the tooltip from the hidden charts

Probably not an issue, since the developer has clearly spent time on this, but working with the trimmer is not pleasant:
1. It can never stay on one position, once u decrease a range to the minimum from one side and start decreasing from the other side-> it would start moving as well. Thus, if i want to focus some range i cannot just set the left border to the left bound and the right border to the right bound, because the trimmer will move my range.
2. overall it behaves "drunken" for the lack of a better word

In general the app is good except:
- the obvious crashes
- drunken slider
- slight underperformance on line graphs, especially on the zoomed in 4th chart

I like what u did with the tooltip on the edge automatically scaling the chart. Very nice idea, i put like.

1) press 2 buttons under the graph;
2) wait until the graph started to glitch
3) scroll the app
4) it's crashed

The app crashes.

The variation of this crash was described above, however not completely. The issue that i am describing actually happened to me and then i went to read all the previous issues to see if it was described.

While holding the trimmer for some time (not just scrolling fast) for some reason the zoom button stops working instantly and waits for something. I thought i just removed my finger from the button, and it got left highlighted, so i clicked again and it crashed.

View with values jumps back and forth all the time.

Dates are clipped

Need animation or fix width - very more fluctuations tooltips

X label animation is also wrong, appeared labels should not change as shown in Stage 1 video. Here all labels change change values when scrolling.

laggy on iphone 6 (

101%

not implemented correctly. there is no 3 days

3 + 3 + 7 + 11 + 33 + 44 = 101 ?? Come on ) There are a lot of algorithms to round percentage. like
 https://en.wikipedia.org/wiki/Largest_remainder_method

Highlighting of pie chart parts is not implemented.

Long tap on any filter is not implemented

Line is not centered above the time label.

Sorry, long tap on any filter is implemented, my bad. Cannot delete the issue for some reason

Initially there are 6 lines like design requires (even though it is in wrong scale, it is supposed to start with min value not 0). Then when scrolling for no reason a 7th line appears on top with 4500 value.

After table is scrolled to top and you call the "values view" on the top graph, you will not be able to scroll the table anymore if the scroll startw inside the graph cell. The cell eats the touches and does not allow scrolling up and down.

Hey man. Nice catch on supporting different color sets for day and night charts. I mean lines, buttons and tooltip colors from color documentation they've shared. Literally the one and only app I saw which has it implemented.

Button check images are wrong positioned after theme changed and pressed.

Does not support iOS 8. Telegram does.

Tooltip goes beyond limits

Tooltip blinks during night/day transition

Scrolling is not smooth on iPhone 5

Major: Graph animation has begins with noticeable lag. Thus this contestant tries to hide missing frames.

Major issue: 45 fps during 1st graph scaling on iPhone 6+, 30 fps on iPhone 5.

Major issue: sometimes date labels just blink instead of animate their positions. Not only the UX is suffering, but also it gives this contestant a major advantage in performance over other participants.

Major issue: minimum value is always 0. Not only the UX is suffering, but also it gives this contestant a major advantage in performance over other participants.

Endless vibration of the device when i hold any filter button

All charts, except percentage, must have exactly 6 horizontal lines

Percentage chart must have 25% step

Line charts must start from minimum value, not from 0

Dates on x-axis is wrong

Yellow labels on the y-axis are displayed when the chart is hidden

Tooltip flashes and disappears
