[Gnuplot-info] basic processing of data

[seb_kramm <seb...@ya...>]

Hello,

I have a very basic problem with gnuplot 4.2, searched the doc and the list, but 
found no answer.

I have a ascii data file, two columns, I want to plot the data as points, and also 
plot the value of accumulated data, say the sum of y, or (more exactly) the cumulated 
error for all the points
(sqrt((x-y)*(x-y))

Is there any way to do this without external processing (as described in 6.2 in the 
FAQ) ?

Thanks
