Ya, the problem is my data is pairwise interaction so need to do xlabel and ylabel with 'A', 'B', 'C' respectively.
pie chart need to turn axis on to show xlabel, but it will also show axis line.
set 'Xtick' to  removes the tick, but it still preserves the black axis line.
set 'XColor' into 'w' makes line invisible, but will also make the xlabel into white.
just wanna share my current finding.
And very useful code
rate it now :)

Automatically apply x and y labels to subplots only along the edges.
