Plot table.txt fails in mumax3.10 on Ubuntu 18.04 #228

Closed n-s-kiselev closed 5 years ago

The plot for table.txt does not work in the web GUI. The inspection of the webpage element "plot" returns: "Could not load the image". The issue does not depend on the web browser or version of gnuplot.

If you run the following command in a terminal, does it return an error message?

gnuplot -e "set term svg size 480,320 fsize 10"

n-s-kiselev commented 5 years ago

Yes, it does:

$ gnuplot -e "set term svg size 480,320 fsize 10"

set term svg size 480,320 fsize 10
                          ^
line 0: unrecognized terminal option

One walk-around is to remove fsize 10 from plot.go: args := []string{"-e", fmt.Sprintf(set format x "%%g"; set key off; set format y "%%g"; set term svg size 480,320; plot "-" u %v:%v w li; set output;exit;, a, b)} //args := []string{"-e", fmt.Sprintf(set format x "%%g"; set key off; set format y "%%g"; set term svg size 480,320 fsize 10; plot "-" u %v:%v w li; set output;exit;, a, b)}

Cheers.

@n-s-kiselev Thank you for filing this bug.

I could reproduce this bug with gnuplot 5.2. Everything worked fine with gnuplot 4.4 on my machine though. I fixed the bug (see cb63da14) by avoiding the use of the fsize keyword which became obsolete somewhere between version 5.0 and 5.2.

If this bugfix does not work for you, feel free to reopen this issue.

Thank you, Jeroen! I do confirm that it works with gnuplot v4.4.4 now, but it still fails with gnuplot v5.2.x.

JeroenMulkers commented 5 years ago

Strange. On my system it works with gnuplot 4.4.4 before and after the fix, and with gnuplot 5.2.2 and 5.2.6 only after the fix.

Assuming that you recompiled mumax3 correctly, than the bugs you encounter before and after the fix are system dependent bugs because I am not able to reproduce them.
