Thanks you for review!
1) Yes, i remove animation from tooltip values becuase it has very bad performance on old android device
2) About percents - i didnt notice this and made a percent output on the right, without outputting real columns values. This is an important flaw, thanks for your attention
3) For Y axis labels to round i use .toFixed(0) or .toFixed(1). I think it a cross-browser problem, because in Win/Chrome i have 840, 795, 750
4) Yes, i hate my implementation of X axis animation
Bars: when zoom-out I see blank chart

Thanks you for review!
Yes, there is such a problem due to the fact that the mini map captures several points behind the selector. In this case, to the left of the selected area there is a peak of the graph, due to which the scale of the visible part has decreased

- date range has 1 "extra" day
- small chart on #5 is not as on screenshot
- date range should be replaced by date, when zooming chart #5
- tooltip on chart 5 is not as expected (check screenshot JS_9)
- I'm getting freezes on 6x CPU slowdown (Core i7 7700), maybe someone can confirm

Thanks you for review!
1) Yes, i get +1 column for output selected dates range
2) I dont understand what you meant
3) In video example this is so, but in my implementation after zoom i show average values for selected in main chart period
4) Yes, its my biggest mistake, you right
5) In 6x slowdown there may be freezes and lags, especially on #3 and #5 charts with more calculations

Thanks you for review!
It not visible, because it has very small values in compare with other types. If you hide all types except mango and pears you can see red data
Line charts: in preview not started from min value

This issue repet problem "When selecting preview to right/left chart is still wider than preview", because overhang width in bars chart depends from bar width and makes up half of column width
Nobody added any issues yet...
