Changing scale in plot

Greetings friends,

I want to change the scale of Y axis of first figure as that of second figure, i.e I want the scale to be in terms of 10^-3 to have better consistency..I have attached the code for this plot in below section. I would appreciate your help please.

Wind_resource_SOP=zeros(105120,1);
for kk=1:length(Windspeed_mps_inrange)
    Wind_resource_SOP(kk)=(0.5*Air_density*(1)*Windspeed_mps_inrange_cubed(kk));  %(w/m^2)
end
Hourly_Wind_resource=((sum(reshape(Wind_resource_SOP*5,12,8760)))/60); %W/m^2
Hourly_Wind_resource=Hourly_Wind_resource';

figure
plot_2_x_axis=(5/60):(5/60):8760;
plot_2_x_axis=plot_2_x_axis';
plot(plot_2_x_axis,repelem(I_total/1000000, 12),'Color','y') %  MW 5 min interval
hold on
plot(plot_2_x_axis,Wind_resource_SOP/1000000,'Color','b')% MW 5 min interval
hold on 
plot(plot_2_x_axis,(repelem(I_total/1000000, 12))+(Wind_resource_SOP/1000000),'Color','k') % MW 5 min interval

xlabel('Time (Hours) ','FontSize',16) 
ylabel('Total Power Available (MW/m^2)','FontSize',16)  
plot2_1=sprintf('Solar Resource');
plot2_2=sprintf(' Wind Resource');
plot2_3=sprintf(' Wind + Solar Resources');
legend(plot2_1,plot2_2,plot2_3)
set(legend,'location','best','FontSize',14)
%title('Available Solar And Wind Resources ');
set(gca,'FontSize',20)

You could try setting the Exponent property of the first figure.

x=get(gca);
x.YAxis.Exponent = -3;

It worked, Thanks..
