Step_size = [5 10 15 20 25 30 35 40]; % bottom x axis
FMC_models = [7650000 3830000 2550000 1920000 1530000 1280000 1100000 960000];

PMA_models = [26 26 26 26 26 26 26 26];
PSA_models = [10000 10000 10000 10000 10000 10000 10000 10000];
%% need to use semilog y axis
Initial_trial_force = [0 500 1000 1500 2000 2500 3000 3500]; % top x axis
FMC_models_1 = [960000 840000 710000 600000 460000 340000 210000 90000];

Try this

Step_size = [5 10 15 20 25 30 35 40]; % bottom x axis
FMC_models = [7650000 3830000 2550000 1920000 1530000 1280000 1100000 960000];
RIA_models = [3689 1853 1232 935 747 624 545 463];
PMA_models = [26 26 26 26 26 26 26 26];
PSA_models = [10000 10000 10000 10000 10000 10000 10000 10000];
%% need to use semilog y axis
Initial_trial_force = [0 500 1000 1500 2000 2500 3000 3500]; % top x axis
FMC_models_1 = [960000 840000 710000 600000 460000 340000 210000 90000];
RIA_models_1 = [463 442 398 350 297 244 171 66];
labels1 = {'FMC models', 'RIA models', 'PMA models', 'PSA models'};
labels2 = {'FMC models 1', 'RIA models 1'};
figure();
ax_bottom = axes();
ax_bottom.YScale = 'log';
hold(ax_bottom);
plot(ax_bottom, Step_size, FMC_models, ...
    Step_size, RIA_models, ...
    Step_size, PMA_models, ...
    Step_size, PSA_models);
legend(ax_bottom, labels1, 'Location', 'northeast');
