I have a graph that displays individual test results for a selection of samples. On this dot plot I have added reference lines so the user can type in the percentiles they would like to look at. Off to the side of the dot plot I would like to display the average and standard deviation of the samples that fall into the respective reference lines. In other words, when the user changed the percentile values for the parameters I would like the average and standard deviation to change with it. Is this possible, to create a calculated field that adheres to the parameter selections?
