Octave plot is not correctly printed in pdfcairo - plot

Question

I'm trying to subplot my data, but printing in PDF brings results I can't use: Title and x-axis title are cut (and the legend's box is covered by the graph, but I can handle this with other positions). I have to use gnuplot and pdfcairo because other seup isn't working with special characters, umlaut, etc.
clear;clc;close all;clf;clear all;
graphics_toolkit("gnuplot")
x = 0:.1:10;
y1 = exp(-x).*sin(x);
y2 = exp(x);
h=figure(1);
subplot(2,1,1);
plot(x,y1)
h1 = plot(x,y1);
set(h1,'LineWidth',4)
set(gca,'FontSize',32)
set(gca,'FontName','Times')
set(get(gca,'Ylabel'),'String','TTEST test \rho \rightarrow','FontWeight','Bold','FontSize',32)
set(get(gca,'Xlabel'),'String','abc / - \rightarrow','FontWeight','Bold','FontSize',32)
legend({
'h_{ref}(t)'
},"location", 'northeast');
title('TITLE')
l1 = legend;
set(l1,'FontName','Times')
subplot(2,1,2);
h2 = plot(x,y2);
set(h2,'LineWidth',4)
set(gca,'FontSize',32)
set(gca,'FontName','Times')
set(get(gca,'Ylabel'),'String','TTEST test \rho \rightarrow','FontWeight','Bold','FontSize',32)
set(get(gca,'Xlabel'),'String','agc / -\rightarrow','FontWeight','Bold','FontSize',32)
legend({
'h_{ref}(t)'
},"location", 'northeast');
l2 = legend;
set(l2,'FontName','Times')
print ('title_axis.pdf', '-dpdfcairo', '-S1000,600');
