– Overall speed is slightly above average.
– The third graph blinks and jitters when filtering.
– Bonus goals are implemented (+), however parts of expected animations are missing and filtering (graph #4) is broken (the attached video).

(The attached video was incorrect and we updated it. We're deeply sorry for the confusion.)

Animation jumps if enable/disable two lines

Yeah, you're right, there is a jump. However I think it still works quite well for such usecase.

Can't select box for 6.04.19., no animations on date and values labels, label for aggregated values is not present

Android 9, HUAWEI P20 pro

Yeah, sorry about that, I forgot the aggregated value indicator. I skipped on animations because they affected performance too much.

Selection goes to another piece of pie if disable line. It MIGHT be a feature, but tooltip window closes, so I assume it's a bug. (Please also see next issue, they are related I believe)

Yeah it's a bug, sorry about that. And sure, these two issues are related.

Denis Apr 18, 2019 at 18:44

It's possible to select 2 pieces of pie (or even each one)

You're right, there is a bug with hiding chart pieces while a piece is selected. Sorry about that...

no enable/disable animation under range-selector

Not sure what you mean. Seems fine to me.

Chart under range selector blinks when enable/disable lines

Night Deer Apr 23, 2019 at 17:19

You're right, there is a blink due to alpha animation. Thanks for noticing.

Poor performance when enable/disable lines multiple times

Nexus 5 / Android 6

Night Deer Apr 23, 2019 at 17:19

Well yeah, Nexus 5 is a pretty outdated device and you also have GPU inspection overlay drawing over the app. I have also tested the app on a real Nexus 5 device and generally it worked smoothly. I'm sorry you got the performance issue.

97%

It is intended behaviour. It is not always possible to distribute the remain correctly. Imagine you have three equal parts: 33.(3)%, 33.(3)%, 33.(3)%. Should you really display it as 33/33/34 just in order to make a sum of 100? I don't think so.

Denis Apr 18, 2019 at 18:39

No able to select multiple days in a zoomed mode, discrete selector is static.

Night Deer Apr 23, 2019 at 15:16

This is intended behaviour. Demo video had such option only for the pie chart so I implemented it there. It's not clear how to implement multiple days display for line charts so I skipped on that.

Denis Apr 18, 2019 at 18:46

It's possible to see wrong tooltip (Apple selected, but orange in tooltip)

Xiaomi A1 / Android 9

Night Deer Apr 23, 2019 at 17:17

Thanks for noticing, not sure how you caught that. It seems like the same bug as one that you have already reported above.

Denis Apr 18, 2019 at 18:46

Too much grid lines

Xiaomi A1 /Android 9

Night Deer Apr 23, 2019 at 15:18

That is easily configurable. Now it is configured to my choice and I think it looks well.

Good app, you are in my 'vote up' list. Vote up mine, if it's good enough
