Owning Palette: Control Charts VIs

Installed With: Statistical Process Control Toolkit. The objects available on this palette vary according to the packages you have installed.

Use the Control Charts Drawing VIs for graphing control charts and raw process data.

Palette Object	Description
Draw Chart with Variable Limits	Given an array of control chart points, arrays for the upper and lower control limits, and the control chart limits cluster as created by the chart VIs, creates a variable limits control chart (XY graph indicator). Use this VI with the u chart and p chart if the number of inspected units is variable.
Draw Chart with Zones	Given an array of control chart points and the chart limits cluster as created by the chart VIs, creates a control chart graph (XY graph indicator) with points plotted against zones. This VI is useful when visually applying run rules to a control chart.
Draw Control Chart	Given an array of control chart points and the chart limits cluster as created by the chart VIs, creates a control chart (XY graph indicator) with points plotted against upper and lower control limits and center line.
Draw Run Chart	Draws a run chart of the individuals making up the samples X array in time order. The VI interprets the individual observations in the samples array to be in time order by row, and the individuals within each row by column. Optionally, the VI plots the specification limits and/or the natural process limits against the observations.
Draw Tier Chart	Draws a tier chart (also known as a tolerance diagram). Plots the spread of the observations in each sample. Optionally, the specification limits and/or the natural process limits are also plotted against the observations.
