Export LTspice plots to Matplotlib

LTspice to matplotlib plot

This code snippet allows exporting an LTspice plot to Python and visualize it using Matplotlib.
This transposition is useful because it allows further manipulation over the dataset, which turns out to be often intricate within LTspice itself.

Usage:

plot:

Once exported the data from LTspice in a .txt file, just type:

python plot_LTspice.py dataset/dataset/Draft2.txt

fft plot:

Make sure to export the data as (re,im) and not (mag, arg) although the final plot will be of course a polar plot. Save the dataset as a .txt file as well – (actually .fft.txt) and type:

python plot_LTspice_fft.py dataset/dataset/Draft2.fft.txt

to visualize the plot.
