Hi @dvkruchinin

Probably we need to test statistics feature. After quick view of tests I didn't find anything related.
Let's say create several shapes/tracks (including interpolation) of each of rectangle, polygon, polyline, points, cuboid, tag; then open statistics and be sure it shows valid results.

Hi @bsekachev
This test scenario was proposed based on a code coverage analysis. Of course I will prepare this test.
