Administrators Telegram, where my graphics? Yesterday I sent a zip archive, but I do not see my work in the list
mode change does not work correctly
Lines dots (circles) on preview that appear when you move the mouse behave incorrectly for the first chart when any of the lines is switched off, but at the same time works correctly in the second chart.
(When empty the tooltip is still displayed, but probably this one could be ignored.)
Chrome 73
It is impossible to select less than almost a month on daily graphs. Initial date range selected is almost half a year. (1 Apr to 30 Apr in the screenshot imply that the initial range should be final month)
Chrome 73
Percentage chart. Display incorrect data. Zoom-in + uncheck + zoom-out. After hover chart it's fixed, but after this hover pop-up has incorrect data too.
Mac os - safari, chrome.
In timeline (navigator) for pie chart there are only 6 days available.
Wrong dates in the title for pie chart.

The drag/resize functionality of the magnifier (search box of the navigator) has minor glitches.
Chrome 73
No tooltips and separation of sectors on hover or touch or click on the pie chart pieces.
Chrome 73
For single column chart in zoommed in mode the timeline (navigator) is still displayed, but the new buttons for new lines are not displayed.
Also the View button is displayed, but this is a minor thing and can be ignored, I think.
Chrome 73
The stacking of the stacked bars is upside down starting from the lowest values at the bottom and putting the higher values to the tops.
Chrome 73
Impossible to select in preview the extreme right value (sometimes couple of them - depends on the current range selected)
Chrome 73
No percentages displayed in the tooltip of the pointed position in stacked percentage chart
Chrome 73
Wrong format of the dates displayed in the title for zoommed in mode of any chart. (Probably a minor thing and could be ignored)
Chrome 73
Unable to select time range by dragging in the preview area (outside of the current window).
Issues with pie chart.
The functionality is broken when zooming in on dates at the beginning or at the end of the chart.

Glitches with main percentage chart tooltip when showing pie chart.

Very difficult (almost impossible) to enter zoomed mode for pie chart with mouse at the left half of the chart.
Chrome 73
The scaling of lines of y_scaled chart doesn't seem correct. The max value of one line should correlate with the max value of another one at the top on 100% date range.
Chrome 73
Issues with zoom in on last but one date of the chart for line charts and bar charts. The final date is impossible to select.
