summary
Concrete gnuplot workflows for data analysis: reading CSV files (handling decimal commas by replacing them or using set datafile separator ','), selecting and plotting columns with using, interactive zooming and HTML export that shows x/y under the cursor, exporting reproducible PostScript/PDF via set terminal postscript color and replot with an output file, performing least-squares fits and residual plots (example fit giving slope ≈ 1.17e4), and automating measurements into scripts or a serial microcontroller terminal.
