Data to graph

Hi everyone,

I have a lot of points that I want to make a line graph for. I have it working just the way I want but I want the data to change based on the number of points I have and the number of points can change from version to version. For example, the first day I might have 80 data points so my range goes from $A$1:$A$80. The next day I might have 115 points but I don't want to have to go in and change the cell references each time, I want the graph to just be able to tell how many points there are and change the references accordingly. Is this possible?

Thanks!

Will
