data points with yerrors in pdfcairo terminal

I am plotting data with y-errorbars on a pdfcairo terminal and have a problem to properly size the data points:

plot "test.data" u ($6) : 10 : 11 with yerrorbars pt 7 ps 0.5 t

ps 1 gives too large a point and decreasing ps gives strange results. Interestingly, on a windows terminal everything looks ok, but the pdfcairo terminal makes problems. What is wrong?

Solution

  • Hmm. I see a problem also but I do not know what causes it.

    Workaround Plot the data twice, once to show the error bars and once to show the variable size points. Here is a screenshot of the pdf output using gnuplot 5.4.4

    set term pdfcairo
set output 'yerrorbar.pdf'

set sample 51
set xrange [0:1]

set key left reverse

plot '+' using 1:1:(0.2) with yerrorbar lc 'blue' pt 7 ps 0, \
     '+' using 1:1:1 with points lc 'blue' pt 7 ps variable
