How to extract point data.

Show all headers | View raw

I have a data file containg values of X and Y data.

Example (Y = 2X)

X	Y

1	1
2	4
3	6
4	8
5	10
6	12

When I plot the data I get a nice curve.

However what I want is to get the Y-value for a given X-value. Is it possible to extract.

Additionaly, the (X,Y) pair may not be explicity present in the file.

For eg X = 4.5 in the above case. Is it possible to get the Y value for X = 4.5 from the above data set and store it in a variable.

Thanks in advance
