I have data that is 3x200 I need a xbar and r chart with control limits.

I have the data as a .m file. I copied the data from the varibles tab and pasted it into the varible x. So my x varible is a 3x200. Then this is my code to attempt to get the charts needed. plot= controlchart(x,'charttype',{'xbar','r'}) I then get this error,

Error using controlchart>errorcheck (line 972)

WIDTH cannot be larger than the number of points.

Error in controlchart (line 228)

errorcheck(X,ngroups,label,lambda,limits,parent,cctypes,nsigma,...

Error in Untitled (line 2)

plot= controlchart(x,'charttype',{'xbar','r'})

and cannot figure out how to fix it. Anything helps! Thank You!!

Answer 1

[Mahesh Taparia]

Hi Brady

You are getting an error of some size mismatch of your input data. The variable ‘x’ is having a size of 3X200. The error can be overcome by replacing x by transpose of x in controlchart function as the size becomes 200x3 and width criteria can be satisfied. For example,

plot= controlchart(transpose(x),'charttype',{'xbar','r'}) 

For more information you can refer to the documentation of controlchart here.
