    _______________________________________________________

Details:

ubuntu 16.04 and dev. and default qt graphics.

There are three things that all must happen to show this bug.
1) must have at least 2 subplots.
2) the x data range must be < 1e-3
3) the xlabel must be before the lines are drawn

With these 3 conditions then the plot is wrong( blank)

You can use this code to explore the 3 conditions.



x=[0:4] * 1e-4;
for k=1:2
subplot(2,1 ,k)
xlabel("hi")
hold on 
plot(x,rand(5,3))
hold off
#xlabel("KK")
endfor
