This is our starting situation

jthi_0-1712584851092.png
We create new column which concatenates bucket and corner
jthi_1-1712584880761.png
We then build X-axis such as way that corner is on lowest level, middle our new column and highest bcket
jthi_2-1712584966679.png
Then we double click on x-axis hide our new column
jthi_4-1712584998866.png
right click and order by desc
jthi_5-1712585022235.png
jthi_6-1712585032737.png
Depending on your data you might have to modify your order statistic.
Or do you wish to have something else as your final layout?
