Create an Assessment Map to display a "heat map" of the plot values in the current data column.
The Box-Whisker graph shows the 'spread' of treatment data around the median, using a 'box'
and 'whiskers' to break down each data group by percentiles.
ARM has another tool for statistically finding outliers – Column Diagnostics.
The value can also be thrown out of the analysis, by marking the plot as Damaged.
