— Overall speed is slightly above the average.
— The app is sloppy on the last graph when filtering and scaling .
— The third graph blinks and jitters when filtering (the attached video).

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

Disagree with that issue. That point was not specified by any telegram rules. It is neither bad nor good. Just a feature.

Chart 1. Good performance. Correct auto height wrap logic.

ISSUES.
1. No clip area. It is not difficult to add but it will drop a few frames. So I found this as a performance hack and thus this could be an issue.

Some elements are drawn on top of chart navigator

Weird jumping and blinking Y-axis label animation, the labels sometimes appear below the preview chart.

Nice app, but unfortunately critically slow when changing time range on graph #5.

The performance of the last chart is not great.

The date labels overlap the chart title.

Night mode icon not as in design

No points "run" animation on selection change. It is shown on the demo gif. Also, no point card position animation.

2. Not a big issue. But overall dialog is slightly different from the design provided. Good point is values and date change animations. See previous screenshots (issues 1)

1a. Also no clip area
3. Y Scaled Chart. Wrong animations (appear/disappear). Also, buttons are locked during animations, which could be judged as a hack, because animations that are interruptible and reversible way more difficult to implement. It also requires additional logic and may influence performance.

4. No data sorting by descending in date dialog (applied to most participants).
5. Edge dates (eg. "17 May") in dates bar below main chart area are removed/clipped abruptly. Should be removed/clipped only when offscreen. (this issue also applies to many other participants.)
6. "Pears" (filter others) issue. Animation rough.
7. Stack bar edge shift issues. Start/End offsets of the chart are different depending on the current scale (wrong shift calculation due to different absolute bar width at a specific scale X). (this issue could also be found in some other participant apps).

1. X axis labels are drawn semi-transparent when user doesn't interact with the app.
2. By design area chart must have 4 Y axis lines instead of 5/

1. All label must not be shown for this chart.
2. Dates label at the top is not animated.
3. Selection box has no shadow.

1. Some wrong white vertical line is drawn in navigator.
2. Wrong position of rectangle with selected values. By design it must overlap the vertical line when there is enough space to show selected circles under the rectangle.
