Hi


I need to make a line graph for someone at work. Mostly i don't have any problems with it, but this one is a little bit more difficult.

What I need

On the vertical line i need 3 categories (1, 2, 3) with each 7 subcategories (w, k, m, wk, wm, km, wkm). On the horizontal line i need dates. (p.e. 2/2/2011 until 5/2/2011).

I added a drawing to make sure you can understand what i mean. (click on "drawing")

Each date there can only be used 1 subcategory.

Can someone tell me how i can make this line chart?


Many thanks in advance!


Kind regards
