If my test have spec =0, when i plot the variability plot, the 0 line will become dotted line with grey colour instead of blue solid line. Other test that spec which is non zero don't have this issue. Why is that ? Anyone advice me? Thanks
This appears to be a bug in JMP. You can get around it by specifying your LSL as .000001, and it will show up. Please submit the issue to JMP Support, firstname.lastname@example.org.
