gnuplot does not typeset the y-label

Question

I use gnuplot 5.4.5 for processing the following script:

set key enhanced font "Monospaced,13"
set grid

set style line 1 \
    linecolor rgb '#a82828' \
    linetype 1 linewidth 3 \
    pointtype 5 pointsize 1.0

set xlabel "Entropy"
set xrange [-0.05:1.05]
set ylabel "Amortized work"

set terminal png enhanced font "Monospaced,13" size 500,350
set output 'EntropyToAmortizedWork.png'

plot 'EntropyToAmortizedWork.dat' with linespoints linestyle 1 notitle

replot
exit

The file EntropyToAmortizedWork.dat lives here.

All in all, I get:

Clearly, we have a typesetting artifact. How could I deal with it?

Answer 1

I can reproduce this on Win10 with gnuplot 5.4.5 and terminal png, but not with gnuplot 5.4.4. Even terminal pngcairo seems to have a problem with 5.4.5, check the missing horizontal lines on some xticlabels.

So, suggested solution would be to go back to gnuplot 5.4.4 or earlier versions.

This would be a minimal script (no need for data).

Script:

### wrong ylabel with 5.4.5 and png terminal
reset session

set ylabel "This is the y-label"

set term png size 640,384
set output "SO74179232_png.png"
plot x

set term pngcairo size 640,384
set output "SO74179232_pngcairo.png"
plot x

set output
### end of script

Results:

gnuplot 5.4.5, terminal png

gnuplot 5.4.5, terminal pngcairo

gnuplot 5.4.4, terminal png

gnuplot 5.4.4, terminal pngcairo
