Hi all, im trying to plot data of 4 (1×1 double Timeserie) vectors i use the code below
c=title('Einfluss der Geschwindigkeit auf den Energieverbrauch ');
b=xlabel('Zeit in [ms]');
a=ylabel('Energieverbrauch des Hauptantriebs in [KW]');
set(a,'FontSize',15)
set(b,'FontSize',15)
set(c,'FontSize',15)
set(gca,'FontSize',14);
axis([0 1030 50 63])
plot(E_Real_Hauptantrieb_130.time,E_Real_Hauptantrieb_130.Data,'-ob');
grid on;
hold on;
plot(E_Real_Hauptantrieb_100.time,E_Real_Hauptantrieb_100.time,'-og');
grid on;
hold on;
plot(E_Real_Hauptantrieb_80.time,E_Real_Hauptantrieb_80.time,'-or');
grid on;
hold on;
plot(E_Real_Hauptantrieb_60.time,E_Real_Hauptantrieb_60.time,'-oy');
grid on;
hold off;
legend('130 km/h','100 km/h','80 km/h','60 km/h')
but Matlab always crash or show me a black screen Figure does any body know why ?

To plot in the same figure use SUBPLOT. Something like this:
figure;
subplot(2,2,1);
plot(E_Real_Hauptantrieb_130.time,E_Real_Hauptantrieb_130.Data,'-ob');
subplot(2,2,2);
plot(E_Real_Hauptantrieb_100.time,E_Real_Hauptantrieb_100.time,'-og');
subplot(2,2,3);
plot(E_Real_Hauptantrieb_80.time,E_Real_Hauptantrieb_80.time,'-or');
subplot(2,2,4);
plot(E_Real_Hauptantrieb_60.time,E_Real_Hauptantrieb_60.time,'-oy');
Then adjust legends and whatever for each subplot.

Consider this line for example:
plot(E_Real_Hauptantrieb_130.time,E_Real_Hauptantrieb_130.Data,'-ob');
Being the two vectors E_Real_Hauptantrieb_130.time and E_Real_Hauptantrieb_130.Data too big, Matlab crushes or do not show you the plots. So, you can downsample them (meaning that you can extract only some values from the vectors) so that you can decrease their size. For example try:
plot(decimate(E_Real_Hauptantrieb_130.time,100),decimate(E_Real_Hauptantrieb_130.Data,100),'-ob');
