Color in Reports shouldn’t change

In the Report “translations after month” I see all my income and outgoing.

The first 10 categories shouldn’t change the color of the circle⭕️ diagram.

This would be much clearer to see where for example the category “car” or the category “outside food”(McDonald’s,bk,…) in comparison to the month before are.

The color stays for the 1. Place 2.place 3.place every month the same. And one month is car in 1.place with color red and next month it is in 4.position and have another color.
With that kind of diagram it is impossible to compare the months!!!
