A bit more info'
This is one I just knocked up
It might be easier to highlight one set of values, e.g. Values in column A, then select from "Insert" select the line graph from the options
Choose the first one in the list to start with
This should give you a graph with your highlighted values and nothing more
Then you can play with selecting your other data ranges
Right click in the graph area, and you'll have a choice of selecting the data
Then you can play about with the data ranges and the labels.
To format the graph with additional info', click on the plus sign at the top right
And you'll get the panel at the left (depending on screen position of course) and as you use your pointer down the list of options, you'll see the differences it makes.
It'll probably take you some playing about with it to get familiar.
Then you can move onto more impressive presentations.
