This example uses the GPLOT procedure and the OUTLIMITS= data set FAILLIM2 from the previous example to plot an OC curve for the p chart shown in Output 38.4.3.

you draw a line that follows the general direction of the curve at that point. An example of this can be seen below. Once the tangent is found you can use it to find the gradient of the graph by ...

This example uses the GPLOT procedure and the DATA step function PROBNORM to plot operating characteristic (OC) curves for charts with 3 limits. An OC curve is ...
