plotting several arrays in one graph

Dear all,

I have a problem plotting several arrays in one plot.

Can't figure out why only the last two arrays are shown in the graph

figure
plot(dt_hourly, QLR_actual, dt_hourly, QLR_Haude, dt_hourly, QLR_Penman_original, dt_hourly, QLR_PenmanFAO, dt_hourly, QLR_possible, dt_hourly, QLR_Turc, dt_hourly,QLR_zero )
legend('Q_L_R with actual ET', 'Q_L_R with ET after Haude', 'Q_L_R with ET after original PM', 'Q_L_R with ET after Penman Monteith FAO', 'Q_L_R with max ET', 'Q_L_R with ET after Turc', 'Q_L_R with zero ET')
xlim([min(dt_hourly) max(dt_hourly)])
title('Comparison of Differently Simulated Runoff Time Series Using Different ETP Methods')

Would realy appreciate your help for this!

Best regards,

Arthur Leon
