I would probably concatenate the Year and Trimester in another column for use as your X variable. You can do this with the concatenate function or using an equation like

=E2&"-"&F2

Where E2 and F2 are the cells you are concatenating.

Selecting the columns (RW, RW%, WIW, WIW%) and using one graph to get the info is beyond my expertise.

I posted here a few days ago and was given some ideas on how to do this.
However, I seem lost. I have a main worksheet which is updated from several
worksheets by using code. On this worksheet is approximately 15-20 columns
something like this.
trimester year RW RW% WIW WIW% etc
1st 2001 80 89% 79 75%
2nd 2001 90 89% 84 87%
3rd 2001 87 88% 92 89%
1st 2002 88 88% 90 88%
etc etc

What I would like to do is create one chart and by selecting the title of
the column from either a combo box or by using a button at the top of each
column have it poplulate the chart with trimester, year and title. Also,
have the title and legend of the chart change to the appropriate information.
Another thing as time goes on information will be added. I looked at pivot
table and a few websites, but can't seem to get anything what I am looking.
Can anyone assist on this? Thanks in advance
