Excel Graph

[lavakugan]

Hi,
I have a graph with x and y values. I have more than 10,000 points.

For an easy example,
Say
x y
1 2
2 6
3 7
4 9
5 11

I like to have a graph with x and y values but eliminate one coordinate. For example, for one condition, I like to remove the coordinate (3, 7). The graph should break in between x values 2 and 4 . With the other condition, I like to remove the coordinate (4,9). What type of condition I should provide?

Thanks.
