I'd like to know how to plot power series (whose variable is x), but I don't even know where to start with.

I know it might not be possible plot *infinite* series, but it'd do as well plotting the sum of the first **n** terms.

## Best Solution

Gnuplot has a

`sum`

function, which can be used inside the`using`

statement to sum up several columns or terms. Together with the special file name`+`

you can implement power series.Consider the exponention function, which has a power series

So, we define a term as

Now we can plot the power series up to the n=5 term with

To plot the results when using 2 to 7 terms and compare it with the actual exp function, use
