+The legend for the Pseudocolor plot is a color bar annotated with tick marks and
+numerical values. Below the color bar the minimum and maximum data values are
+also displayed. Setting the limits for the plot changes *only* the colar-bar portion
+of the plot's legend. It *does not change* the *Min* and *Max* values printed
+just below the color bar. Those values will always display the original data's
+minimum and maximum values, regardless of the limits set for the plot or the
+effect of any operators applied to the plot.
