How to Highlight some distributions in graph
Hello:) The figure above is a part of my question. As you can see at the picture, I want to highlight some elements whose Cpk is smaller than 1.
Somebody help me.. Thank you in advance:)

Re: How to Highlight some distributions in graph
Hi,
Assuming that your data is in stacked format (i.e., Ys = Data are all in 1 column and the Xs = Label are in a second column), create a new column of Row State type and enter the formula below:
If(
Col Mean( :Data, :Label ) - Col Std Dev( :Data, :Label ) * 3 < :Data <=
Col Mean( :Data, :Label ) + Col Std Dev( :Data, :Label ) * 3,
Color State( "red" ),
Color State( "black" )
);
:FORMAT << Copy to Row States();
You can easily fine tune the range of CPK by modifying the Std Dev multipliers (here set to 3 sigma).
I hope this helps.
Best,
