Sloppy vertical scrolling when all the charts are zoomed out to maximum time range. Sloppy horizontal scrolling on graph #3. Glitchy night mode.

# All graphs
- Cannot start scroll of table in the range selector.
- Cannot start scroll of table in area where visibility filters are.
- No distinction between table scrolling and moving finger inside the chart. You can start viewing the values in the chart, and accidentally scroll table at the same time, which will stop you from viweing the values further. This is actually very annoying. Has been reported before, but I provide a video.
- Only the first chart has the title, all others do not.
- Very sharp angles are squared in the end instead of rounded. Not by design.
- No arrow on the values view indicating that you can zoom into it. The potential user that has not read the rules probably would never know.

Multitouch on trimmer handles is allowed, but it causes unexpected behavior

— Big delay on launch.
— Switching themes causes the screen to blink.
—The pie chart doesn't support scaling and doesn't show the box with the details.

crashes on start (iPhone 5)

Chart #1
- When trying to zoom into rightmost value (6 Apr), app zooms you into 3 Apr.
- Bottom line is clipped the one that is at 0, together with the point.
- Zoom out button interlaps with the dates label on iPhone SE.

Chart #5 Overall should have payed more attention to data correctness and functionality. Could be improved upon:
- Highlighting of pie chart slices not implemented.
- When zoomed in, small pie chart parts do not show their values.
- When changing graphs visibility in zoomed out state the value in values view first gets 0% and only after a moment gets updated to actual value.
- The percents seem to always add up to 100 in zoomed out state, not so much in zoomed in state. Select in zoomed out state -> (26Feb, Apples+Lemons+Kiwi+Mango). Then, zoom into 26Feb. So far so good. Select Oranges. Deselect Oranges. Now percents are different from what they have been, when we zoomed in. Not only that, they now do not add to 100, only 99.

Good:
Not bad zoom in animation, seen worse)
Cool visibility update animation in zoomed in state.

Minichart for stacked bar is broken, if u apply some filters while zoomed in, then zoomout - the minichart has wrong colors

Interactions when all lines are hidden on the chart where it shouldn't be possible (according to design).

Sometimes pan for view with values is interrupted by vertical pan of scroll view.

Bar Charts have big lags

Chart #4
- In zoomed out state values view does not show value, only the date. Zoom into 4th graph, deselect all visibility filters, zoom out. The values view also gets so shrinked, that the date seems just floating in the middle of nowhere. The biggest problem here that zooming in from this moment on seems impossible (or you have to really aim to tap into that thin dark line above the date label)

Chart #2
- Sometimes it is impossible to read the graph labels that are blending with the graphs themselves.
- Animation glitсh, when all filters are enabled (on), when you long press on any of them. The graph that you selected with long press is supposed to just stay there, but it disappears for a moment, and then appears with animation.
- The values could have been rounded a little nicer (its actually harder to accomplish) to avoid 30.4k and alike.

Something is really wrong with stacked bar chart filters. Applying them leads to totally incorrect display.
try applying filters while zooming.

Its cool, that you supported multitouch in range selector, respect for that. But if you move one finger past the other and scroll, it looks really bad. I know it is a weird use case, but still.

Preview chart can become single color, and different from main chart. Not sure how I got into this state, but it was stuck in it permanently.

Animation looks bad when quickly changing selection range.

Range selection does not work on zoomed in view of chart #5.

lags/by steps animation until change color mods

1 Pie chart 100% is cut off
2 cannot select range, only 1 day is visible
3. zooming in to pie chart, applying some filters and then zooming out, leads to late percentage chart update
4. scrolling/scaling while zooming in to pie chart will let you scroll/scale the trimmer on pie chart (normally not possible) and update the header dates. However the pie chart doesnt get updated. See video.

p.s. there is a cool minigame you can play to not let the pie become complete. See video 2. like :D

Inconsistent hiding on the second chart. Long tap doesnt hide the axes labels. Normal tap does hide it. This can lead to yellow axis updates when only blue is shown

This is a weird issue, I am not sure this is an issue even, since I am reporting it only for this app and nowhere else.

Try scrolling, scaling, zooming in/out on the stacked bar chart. It will eventually start lagging.

Basically the app uses so much CPU that the device becomes heated in seconds. Let me explain.

At some point I noticed that the charts started lagging, i thought it was a memory leak somewhere or smth. Tried to record it. 

Then realised, that enabling recording itself makes the app lag.
Going into power saving mode - makes the app lag even more.

I have not seen such behavior in other apps, although this is one of the last i am testing now. Thats why i think its an issue.

In general, i think that the app throttles all the CPU so if you would have some music app in the background or use anything else on the phone besides this app the lags would be noticeable.

Maybe the video helps to see the issue.

Using trimmer also deforms it

Does not support iOS 8. Telegram does.

wrong minimum

crazy jumps

Vertical and horizontal scrolls do not cancel each other. It's not user-friendly when you select the dates with tooltip

wrong small chart state

last chart's vertical axis doesn't match the required design

Major issue: 42 fps during 1st chart scaling on iPhone 5S. For more details read my comments about performance of entry213.

40 fps during bar chart scaling on iPhone 5S.

When scrolling through zoomed in chart 3 in power saving mode it just freezes for a good 380 milliseconds, which is massive, it is like 24 frames lost at one time.
