[Gnuplot-info] linear regression x scale, y intercept, slope value

[r <re...@eu...>]

Readers,

I plotted the following data into gnuplot 37:

0.3275910144623710	0.0550704059768284

column 1 is y axis data, 2nd column for x axis. The resultant graph shows the
intercept as being the first data point, 0.005, 0.47!

The x axis shows tics of values 5, 10, 15, 20, 25, when the above data is not
within this range. Y axs shows tics in the right range to the data.

I want to add a trend line to the function f(x)=mx+c for the above data and also
deduce values for the intercept and the slope of linear regression.#

Any help?
