This is the graph i get which is the one I need but now just need to figure out how to print the average of the water vapor concentration on the graph.

Best Answer

yline(mean(site(:,9)),'b-','Mean concentration')  %r2018b or later

plot([min(xlim()),max(xlim())],mean(site(:,9))*[1,1]) % any matlab release

Try :

figure (4)
grid on
hold on % Hold position should be at the start of plotting to overlap plots
plot3(cm_willans,pma_1400,pme_e, '-r','DisplayName','legend-1');
plot3(cm_willans,pma_1900,pme_e, '-m','DisplayName','legend-2');
plot3(cm_willans,pma_2500,pme_e, '-g','DisplayName','legend-3');
plot3(cm_willans,pma_3000,pme_e, '-b','DisplayName','legend-4');
plot3(cm_willans,pma_4200,pme_e, '-k','DisplayName','legend-5');
plot3(cm_willans,pma_5300,pme_e, '-y','DisplayName','legend-6');
plot3(cm_willans,pma_6400,pme_e, '-c','DisplayName','legend-7'); % DisplayName property to set legend name
xlabel('Cm in m/s')
ylabel('Pma in Pascals')
zlabel('Pme in Pascals')
legend show

Hope it helps !
