I love the graph builder, but there is one type of analysis that should be easy, but alas is not. I can easily use the graph builder to add 1 standard deviation error bars, but I am doing some regulatory work that requires 3 standard deviation error bars. It sure would be nice if I could adjust that with a drop down menu. Do you all know of an easy fix for that?
I do not see an option that will allow you to change the STD for the error bars, however, if you standardize the Y variable to where the mean is equal to the current mean, but the STD is 3 times the size of the current STD, then you will get the chart you want. Below is an example showing the use of a Transform formula to show you what I am talking about
