Scatter Plot example:

Let us consider the following sample data for a scatter plot.

Boys (Series 1)		Girls (Series 2)
Age	Weight	Age	Weight
1	72.9	1	72.5
2	81.6	2	80.1
3	88.9	3	87.2
4	96	4	94.5
5	102.1	5	101.4
6	108.5	6	107.4
7	113.9	7	112.8
8	119.3	8	118.2
9	123.8	9	122.9
10	124.4	10	123.4

The following codes create a scatter plot from the above sample data:
