"Stretch" Y-axis data

[Ano Ano]

Hello,

I have a graph with data as follows:

X    Y

0      1

1      4

2      15

3      33

4      48

5      64

.      .

.      .

100       200

 

and I want to "stretch" the Y-axis data like:

X    Y

0      1

1      y2

2      y3

3      y4

4      y5

5      y6

.      .

.      .

100       500

 

ie I want the same y-axis starting point, a new end point and the same number of x-axis points. I dont mind more y-axis points, just to preserve the shape of the curve.

Any ideas?
