Using the current developers sources, this problem can be seen
by ...
clf
semilogy (1:100)
I can't reproduce it here from inside gnuplot.
set log y
set format y "10^{%T}"
set term x11 enhanced
plot x^2
show the expected superscripts.
set term x11 font "*"
or
set term x11 font ",12"
also works as expected
I should have duplicated the effect in a short gnuplot script first.
The one below does not display the exponents.
set terminal x11 enhanced
reset;
set format x "%g";
set xtics font ",14";
set log y
set format y "10^{%T}";
set ytics font ",14";
set xrange [0:100]
plot x
However, this one does
set terminal x11 enhanced
reset;
set format x "%g";
set xtics font ",12";
set log y
set format y "10^{%T}";
set ytics font ",12";
set xrange [0:100]
plot x
I assume that gnuplot is trying to render the exponents in both
cases, but
when the point size does not exist, nothing is rendered?
