legend error

how do i reproduce this? sample figure please! (as simple as possible) :)

I have the same issue. It is caused by ylim([]) if the maxima of the plotted data is outside the ylim() range. The line stroke is then 'cut' into several plots. There's a simple workaround: set the ylim range afterwards in the .tikz figure.

You can reproduce it with the attached matlab sample. The problem only exists if ylim < [1 1] as in the example.

%%%
figure(1)
x=0:0.01:2_pi;
plot(x,sin(x),'b',x,cos(x),'r')
xlim([0 2_pi])
ylim([-0.9 0.9])
Title('\text{tikz test}')
xlabel('\text{x-Values}')
ylabel('\text{y-Values}')
legend('\sin(x)','\cos(x)');
grid on
matlab2tikz('testplot.tikz')

The reason why the graph is split into several smaller ones is to avoid that data that is not visible isn't included in the file. There have been problems in the past where the TikZ files became rather large to the point where TeX would just give up compiling, all based on off-plot data.
I'll see if Pgfplots provides a better remedy there than to add several addplot's.

Fixed; will be part of next release.
