My development strategy was to impement the most hardcore features first. zoom feature is the one.

so at first I implemented Chart 5 + Zoom, only the essence.that's why it doesn't support opening first/last days and zoom when active charts state changed.

then I implemented zoom for Chart 1. it also has side values zoom issue.

The issues you list are the minorest in scope of the contest, in my point of view. So the priority was the lowest.

then the time ended :)
Authors of the contest have forgotten to deploy my app, please do it to make the competition fair.

Even considering on what the focus was done, pie chart doesn't work properly if specific series were selected :)

- Navigation bar is not displayed
- Pie chart is totally broken

I already said about it in prev message. what you are talking about is a matter of 1 hour, while the core logic took me 4 days

Ideally, the ratio of concepts - fucking did not do it myself, but I will shit other works with shit. Dear, tell me, how do you have the right to examine other people's results when you yourself have fully failed?

Thank you!!!
Nice transitions for zoom in!
Sorry you didn't have time to implement other charts, but this work demonstrates that the transitions from the contest requirement can be achieved.
It would be interesting to see the effects on bar charts. Maybe you have some external url with bar charts demo as well?

Thank you! No, I didn't do anything after contest stopped.
Hey! Describe the issue you just found

The issue is with Area to Pie chart transition. if select a day (of course not the latest 3 days or first 3 days, because this is already reported) and then do zoom, then the transition will be fine, and zoom back will also be fine.

but if then consequentially zoom in and back the next day (10 mar, 11, Mar, 12 Mar, etc.), then the animation appearance will break.

this happens, because I don't properly clear the "animation helper" values that are set up on the area chart points before zoom in starts.

these values are needed to set up modification dimensions of the selected day points and the next day points (to modify Y value), so that after animation interval ends, we have a proper corners.

BTW, if somebody wants to adjust Zoom duration, there is this.aiz property which defines the zoom duration. line 13 in the code.
