bar chart - i need to draw a bar chart with + and - temperatures. I want to start on chart on -50 and end on +50. On the graph would you do the bars up only or up and down. I hope this kind of makes sense.

I would do the bars both up and down. Say have a line in the middle (horizontal line) which would be zero, then above that line could be for the + temps and below the line could be for - temps.

thanks - i was not sure whether that was ok, it didn't look right. I have only done it with + numbers before which always start on 0 and go up! Thanks

oops, I see Belinda was using my computer!!!!
