Graphing help

I guess this question should go here....

I wanted to make a graph from a table which contains three columns; the two columns are the variables that i want to compare but the third one is time, so i was unsure of how to include the time column in the the graph, or if i should just lable each point.

any suggestions?


Thanks

How about you have make time x and the other variables y. Just graph both. Then make the lines have a different configuration, i.e. one could be red and the other could be green for the two different y variables. Have a key so you can tell the difference.

Thanks, but if i do that how do i calculate the correlation coefficient?
