Create Statistical Process Control Charts

 Description Create SPC (statistical process control) charts.

Import a data file using the Import Data task assistant from the Tools-Assistants menu, or by entering data at the command line as an Array.

 > $\mathrm{Array}\left(\left[{21}{,}{24}{,}{16}{,}{12}{,}{15}{,}{5}{,}{28}{,}{20}{,}{31}{,}{25}{,}{20}{,}{24}{,}{16}{,}{19}{,}{10}{,}{17}{,}{13}{,}{22}{,}{18}{,}{39}{,}{30}{,}{24}{,}{16}{,}{19}{,}{17}{,}{15}\right]\right)$
 $\left[\begin{array}{c}\colorbox[rgb]{0,0,0}{{\mathrm{1 .. 26}}}\colorbox[rgb]{0,0,0}{{\mathrm{Array}}}\\ \colorbox[rgb]{0,0,0}{{\mathrm{Data Type:}}}\colorbox[rgb]{0,0,0}{{\mathrm{anything}}}\\ \colorbox[rgb]{0,0,0}{{\mathrm{Storage:}}}\colorbox[rgb]{0,0,0}{{\mathrm{rectangular}}}\\ \colorbox[rgb]{0,0,0}{{\mathrm{Order:}}}\colorbox[rgb]{0,0,0}{{\mathrm{Fortran_order}}}\end{array}\right]$ (1)

Plot a C chart.

 > $\mathrm{ProcessControl}\left[\mathrm{CChart}\right]\left(,{100},\mathrm{title}="Nonconformities for Printed Circuit Boards - n = 100",\mathrm{labels}=["Sample Number","Nonconformities"],\mathrm{labeldirections}=\left[{\mathrm{horizontal}},{\mathrm{vertical}}\right]\right)$

Plot a U chart.

 > $\mathrm{ProcessControl}\left[\mathrm{UChart}\right]\left(,{5},\mathrm{title}="Nonconformities in Personal Computers - n = 5",\mathrm{labels}=["Sample Number","Avg. Nonconformities Per Unit"],\mathrm{labeldirections}=\left[{\mathrm{horizontal}},{\mathrm{vertical}}\right]\right)$

Plot a P chart.

 > $\mathrm{ProcessControl}\left[\mathrm{PChart}\right]\left(,{50},\mathrm{title}="Nonconforming Cans - n = 50",\mathrm{labels}=["Sample Number","Sample Fraction Nonconforming, p"],\mathrm{labeldirections}=\left[{\mathrm{horizontal}},{\mathrm{vertical}}\right]\right)$

Plot an NP chart.

 > $\mathrm{ProcessControl}\left[\mathrm{NPChart}\right]\left(,{50},\mathrm{title}="Nonconforming Cans - n = 50",\mathrm{labels}=["Sample Number","Sample Nonconforming, np"],\mathrm{labeldirections}=\left[{\mathrm{horizontal}},{\mathrm{vertical}}\right]\right)$
