Details:

I am not sure this bug is related to octave or to gnuplot.

I have large numbers on an axis whose labels are represented with an
exponential notation and I am using gnuplot as backend. After plotting I want
to change the labels of the ticks with the following command:

set(gca,'yticklabel',sprintf('%.1f|', get(gca,'ytick')))

Most of the time the trick works but for the dataset here attached the ticks
showed in the plot is larger than the set returned by get(gca,'ytick'). This
means that the previous command overwrites only a few of the ticklabels (see
attached figure).

I found a workaround i.e. to put an explicit statement

set(gca,'ytick', get(gca,'ytick'))

before the previous one to clean the ticks. Looking at differences in the
gnuplot generated code it seems a gnuplot command

set ytics add in scale ...

is added after setting the xticklabels. Is the "add" keyword really needed?
shouldn't set(gca, 'yticklabel', ...) overwrite all the labels?
