I'm trying to make a graph with gnuplot. I specified my xrange
, yrange
, and labels
, but when I typed in the following command:
gnuplot> plot "data.txt" using 1:2 with lines
gnuplot tells me:
warning: Skipping unreadable file "data.txt" No data in plot.
I don't understand how my data file is unreadable. This is what my data.txt
looks like:
X Y [I didn't enter X and Y into my text file]
10000 0.030
5000 0.02
1000 0.012
I know I must be doing something wrong -- this is my first time using gnuplot. I tried doing a Google search on how to make a proper data.txt file turns up zilch.
EDIT:
I feel like this may sound strange to ask at a programming Q&A site, but what should a typical text file w/data look like? I'm no computer programmer, just an undergrad trying to plot a graph for her biochemistry class.
