I don't know gnuplot so much and I didn't find valuable information about what I want. I would like to draw a box plot from a data file.
- What is the format of the file?
- Is it needed to compute mean, qc etc.?
What I would like to do is to draw a boxplot (not an histogram). Actually I have xlsx files that I can convert to CSV but I don't know if we can use csv to draw a boxplot. The demos on gnuplot are not really explicit.
plot "file" u (1):2 with boxplot
to plot the data in the second column as boxplot at x=1. All necessary value are computed by gnuplot. – Christoph
