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.
