A friend is wanting to add sigma lines to a graph, similar to what you see in the Capability Animation option under a Distribution Capability Analysis. When we look at the customization script, there are many parameters in there that are not defined such as pMean and pSigma, etc. If I debug the script, I can see these values are appropriately set but where is the customization script getting these values? How can we use similar features for the graph he wants to produce. Does anyone have a way of producing 1 sigma lines across an axis on a one way or bivariate plot?
