If I have a spreadsheet that has the following data:

```
A
0 0
1 2
2 4
3 4
4 6
```

- 0-4 X Axis
- A is Y Axis

First point is `(0,0)`

Second Point is `(1,2)`

Third point is `(2,4)`

Last Point is `(4,6)`

I select my data and do -> Charts -> Line -> pick line from there, it draws the graph of this one table of values. When I draw a chart based on this I get my line correctly. How do I connect `(0,0)`

with `(4,6)`

in a straight line in excel? The reason I need it is because I have some other graphs that are going to be either in one or the other side of the connection line. I need to be able to demonstrate that.
