Good day bros. I have a set of 30 means and associated lower and upper confidence interval values produced by a stats package. I want to plot these (say, a bounded horizontal line with a marker for the mean) stacked on top of one another on a common X axis, so as to compare the means and intervals. I figure one ought to be able to do this with GD Plot. I have used that before but it's not obvious to me how to do this particular task. Can anyone point me in the right direction or to some example code? Searching GD plot confidence intervals doesn't turn up much.
