Gnuplot instant shutdown

[truth is life]

I wrote an octave script to perform some calculations on a data set, and wanted to plot the results. However, when I put 'plot' commands in my script, the result was a gnuplot display opening and then instantly closing, before anything could happen or be seen. I've tried inserting commands to make the script hold there for a long time, like very long loops or user prompts, and I've looked at the octave manual, but I haven't been able to figure out how to successfully plot anything. Anyone here know how to? (I am using octave 3.2.2-2build1 via synaptic)

I don't know about Octave, but the -persist shell command line option of gnuplot will keep the plot window open until you close it. That looks like that is the problem. Without the running "gnuplot -persist", the plot window closes as soon as gnuplot quits or does something else, causing the shutdown you are experiencing.

Well, it turned out the problem was that the file I was editing to try to fix the problem was not the same as the file that was actually being run, since I was using the console history functionality, but had changed the name in the middle. Whoops! :oops:

But now I'm getting a different, weirder error. I modified that same script so that it would put out the data into a .dat file, formatted just the way gnuplot likes it. I try to plot it, and for some reason gnuplot inserts a datapoint which is not actually there in the upper right hand corner! Very bizzare. I checked the files, and they don't have a data point in that exact point
