I realized that MATLAB cannot handle more than 200000 line segments. Is it possible to do somehow?

Please explain the details. If you realize this, mention the reason of your assumption. Post some code, which reproduces, what you observe.

Not sure what you mean by cannot handle more than 200000 line segments. I was able to plot them using matlab 2017b and matlab 2012 using the following code to generate the line segments.
X=rand(2,200000);
Y=rand(2,200000);
plot(X,Y)
However you if you you just want to see the lines you can place nans between each line segment This might improve performance for you.
X=rand(2,10);
Y=rand(2,10);
subplot(211)
plot(X,Y)
X(3,:)=NaN;
Y(3,:)=NaN;
subplot(212)
plot(X(:),Y(:))
I used 10 line segments just to make it easier to compare results
