Details:

Dear all,

with the following code


x = (1:8);
y = 10.^(-50:50:300);
semilogy(x,y)


I see nongnuplot.pdf with the two non-gnuplot graphics toolkits and a correct
plot with gnuplot toolkit. But if I add


set(gca,'yticklabel',{'$10^{-50}$','$10^{0}$','$10^{50}$','$10^{100}$','$10^{150}$','$10^{200}$','$10^{250}$','$10^{300}$'})


I get a lot of warnings such as

line 0: warning: integer overflow; changing to floating point

and a final plot which resembles nongnuplot.pdf. I'm pretty sure that it
worked with 3.8.1 (but cannot check now).

Marco
