Numbers Graphs

[94Dunn]

I recently purchased a Macbook air for university. I'm studying engineering and as a result have to make a graph that shows the change in voltage over a potential divider as the resistance is increased basically i have 76 readings of resistance (X-axis) and their accompanying voltage (Y-axis) but have no idea how to turn all this data into a graph using "numbers". I'm completely new with "numbers" so any help would be greatly appreciated.

You don't describe data, you show data. Two additional things:

1. To graph ordered pairs of values against each other like y vs. x, open your file of values or type them into Numbers. Select the values and press the graph icon. It is easier to do than to describe.
2. As a general proposition, spreadsheets are very blunt instruments for producing graphs. There are a number of superb graphing/charting applications available for the Mac. Many can be used to produce technical and/or business graphs that rival or exceed the work of professional graphic artists.
