Occassionally, when I try to add a trend line to a data series the line is
not displayed on the graph, but a lable appears in the legned box. Any ideas?

At present I want to add a weighted average trend line and so I am having to
do it the long way around (i.e., calculate the average values in the
worksheet and then plot them), but this is time consuming.

Any help would be appreciated.

This may help you:
