One of the tricks I've used to do something like this works well if you
use a chart with connecting lines (either a line chart or a xy scatter
chart). Plot all the points and force the y-max to be whatever you
want. XL will draw a line from the previous point to the top plot
boundary and another line from the boundary to the next point. The two
lines would intersect where the outlier should be.
Depending on the purpose of the chart this technique can be very
effective to show the existence of outliers while still excluding them
from the chart.
