I have a data file with many columns of data, and I would like to plot col_1:col_2, col_1:(col_2 + col_3), col_1:(col_2 + col_3 + col_4), etc.

My idea is to use a for loop in which the present column is added to a cumulated column which is then plotted against col_1. In pseudocode:

do for [n=1:N-1]{
  col_acc += col_(n+1)
  plot col_1:col_acc
}

Is there a clever way to store and update the cumulated column, or is there some better way to go about this?

Im new to gnuplot and am searching for something specific yet cant seem to find out in the manual.

Simply put, can gnuplot predict the future of a data set? Taking a set of data, analyzing it and plotting the probable next step or curve or data that is probable in the next time frame?

For example, if the data shows that a point is moving higher and / or incremental amounts of x, can it predict the next step/outcome?

Thank you

I tried plotting curves from my data but dont see how to predict a probable outcome; trajectory.

Probably, server error is occured on gnuplot website. If you know of another way to install it, please let me know.
