Point Labeling and Chart Plotting help needed

[tacotime]

Well, i'm currently crunching in data for a topgraphic map that is du
tommorow

I've plotted points on a 2-d X-Y Scatter graph, and I want the graph t
label each point with its associated elevation (z value that has
column of its own),
so it'll be easier for me to draw the contour lines later on.

So...
Does anybody know how to label a point ??

Secondly, I want the graph to plot the graph such that the grid lin
spacing is 5cm... how do I do this??

Lastly, is it possible to draw in contour lines with excel???

Any advice, tips, and/or solutions will be appreciated!!
Thanks

hmmm I think I figured out how to do the point labeling (I used J-Wal
tools)

anyways, I still need help specifying the ACTUAL plot size of th
graph... I want both the x and y grid line spacing to be 5cm...

Please Help!
