I'm struggling while trying to plot simple data into a simple chart in Excel (2010 beta).

My data is a very simple one:

```
Value Year
----- ----
1 1900
5 1902
3 1912
```

etc. In the chart, I want year to be the X axis and the value to be the Y axis, and have a single line mapping the change in value over years.

When I select my data, Excel wants to map both at the same time, rather than plotting each pair as a point on the graph.

How the heck do you do this?
