Hi Poni,
Interesting approach .. I will try with our anaylsts (but I do not think they will go for it). The values are product dimensions and this chart is produced as the operator is entering the dimensional data for the product. Operator reviews this chart, looks at the dimensional trend and then adjusts the machine .. we plan to us Histogram and XBAR-MR chart in combination. XBAR-MR chart in MII is very good .. behaves very close to a minitab chart.
I have opened a ticket to SAP and waiting to hear from them. The other thing I noticed is, when you right click on the Histogram and select the SPC results, Cp, Cpk values etc show up as 'NA' which does not make any sense. Even the standard deviation is display as zero.
In any case, can you send me the files to .. 'ghegde@gtweed.com'.
Thanks,
Girish
