I have a scatter plot with about 30 -40 points.

I would like to be able to set the attributes for each point in a
worksheet area. The idea is that points 1-4, 8-9 and 11 could be blue
squares whilst points 5-7, 10 and the rest are green circles. The
problem is that the groups are not contiguous and change from day to
day.

Is this possible?
