Yellow chart is not scaled
Percentage chart is not as it was in task: should be percents with max value = 100
No enable/disable animation for stackedbar chart
In addition, after disabling any line, chart doesn't reflect the relation between lines (see 3rd second of the video, lemons size ~ equals the apples, but two times larger)
