new wks, import Group.dat(\sample\graphing)
new wks again, fill col(A) as row number, set col(B) value as col(A)^2
highlight col(b), make 3D XYY bars plot
==> tick label of X axis is wrong
Open Axis dialog, go to Tick Labels tab.
==> dataset name box was filled with "[Group]Group!A".
Fixed in Origin 2021.
