Thank you for the response.
However the problem I have is thet my graph has 21 series; each is plotted
as a separate line with 4 points (markers). Excell automatically give each
series a different line colour and point marker. I want all the lines and
markers to be identical, but can only do this by moving through each series
in tern and changing the line and marker attributes.
Is there a quicker way?
