— Overall performance is very poor.

— The third graph type is incorrect.
— Sloppy vertical scrolling.
— The app is very slow when scaling, scrolling and filtering.
— Low-quality graphs.
— The app is not optimized for small screens (iPhone 5S)

Upd. Glad to see that you've fixed the third graph!

Completely wrong implementation of the stacked bar chart (lines are used instead of stacked bars)

It's possible to get graph without a... graph.

No retina support (blurry on retina screens)

Graph resolution is obviously too low.
There's also some "breathing" (due to that?) during panning.

Something is wrong with performance/touch input processing is zoom-in mode.

Administrators Telegram, where's my graphics? Yesterday I sent a zip archive, but I do not see my work in the list

Authors, please move my app's data one dir down. Nobody can view my app since it placed not at '/entry211/' and at '/entry211/build/'

Zoom makes chart blinking if selected range is long

When zoom is in progress, it shows hourly values only for the selected day, not for the whole week, how it is shown in task video.

to me, this is ok from user experience perspective BUT:

when you zoomed in, and then made the selection to one week and then zoom back, it looks weird, because it tries to place the whole week to one point of main chart.

Sometimes it crashes. I didn't find a solid way to reproduce it, but fast clicking the chart, tooltip and zoom out button does the trick

"Dear, tell me, how do you have the right to examine other people's results when you yourself have fully failed?"
- everybody has a right to examine other works.


regarding my work. I already provided a message that tells about the issues you listed.

all in all, let's be honest. what you have is:
- rendering of 5 charts, which takes maximum 1 day if participated in the first stage
- tooltips with ugly animations, some redesing, 2 times bolder lines in charts - that takes something like 4 hours
- and of course, the zoom logic of line charts, that is the only challenge in the contest... and it is a bit crappy :)))))

you wanted a video for blinking - here you are :)))

the screen recorder doesn't catch all the frames, but you can see the blink on the 20th second. but it blinks all the time when I use your app

Wrong type of timeline (navigator) for pie chart. No pie chart sectors separation on hover / touch / click. The tooltips for pie chart sectors appear only on touch / click on percentage label, but not on the sector itself.

Three first and three last dates of the stacked percentage chart have broken functionality for creating pie chart.

The views button is displayed for single column chart.

In general not a bad work. No reason to put so many dislikes here. No dislike from me.
