You can just grab the legend's resizing handles and drag it to shrink the
entire legend: Excel tries to redraw the legend's contents dependent on how
big the box is, so squashing it should compresses the line spacing. (You can
also use this technique to create multi-column legends by stretching it
sideways).

This doesn't work if your legend is on a PivotChart, where Excel will
determine the dimensions...

I have a graph with legend, but I can not minimise the line spacing between
the list of items. There are no spaces in the original data that I used and
this has just occured, the other graphs I have created do not have this
problem and I have done nothing different in this graph?
