A really simple solution would be to edit the column property, axis settings.
For the column of interest you could set the min and max axis to just a little outside your spec limits.
If you had to do this for a lot of columns, then a little JSL could help. In this case you could add the axis settings' min and max as the lower and upper spec limit. Check the scripting index for some examples. (Help>Scripting index)
