Graphs - Graphs of Input Data - Probability Plot - Detrended

Select Detrended from the Graphs - Graphs of Input Data - Probability Plot menu to create a detrended probability plot for the indicated variable. This plot is constructed in the same way as the standard normal probability plot, except that before the plot is generated, the linear trend is removed. This often "spreads out" the plot, thereby allowing the user to detect patterns of deviations more easily.
