I understand now how to do the + and - graph but how would i label the 2 axis. One is for temps but how would i show the objects/subjects? If i was doing + only i would put numbers up the side and object/subjects on the bottom line but with + and - numbers it makes the graph look different. Not sure how to label correctly. Please help.
Horizontal line in the middle. Label 0.
+ is up.
- is down.
Then have at the top of the page (or the bottom) a name for each bar drawn. It will look something like this.
 A    B -->etc

I hope this helps. The computer is almost impossible for this.
