I am making a graph, and I have the error bar "points" set to "standard deviation". The error bars present are horizontal, and I cannot figure out how to make them vertical. I've attached a screenshot of my graph. Thanks in advanced for the help!
You should specify what version of JMP you are using.
This looks like a graph where the Standard Deviation is zero. Line of Fit for the summary statistic Mean draws a horizontal line at the Mean, the horizontal line is not a standard deviation.
