when you  use ft_clusterplot  to plot in non parametric statistics


you should watch out  make sure the frequency is just a fixed number like 20 30


if you are use [1:10] or [20 :30]



sorry it will show error like this:  unsupported dimord


you may get confused to fix this bug  just as I do .


that’s beacuse we find everthing is in onrder if you did not notice the frequency.
