Can someone help me fix my axis?

function [] =FFAplot(a,b,k)
a=[2000 1000 4000];
b=[30000 40000 50000];
k=[-.3 -.1 -.4];
for T=1:100
    P=1/T;
    Q1=b(1)+((a(1)/k(1))*(1-(-log(1-P))^k(1)));
    Q2=b(2)+((a(2)/k(2))*(1-(-log(1-P))^k(2)));
    Q3=b(3)+((a(3)/k(3))*(1-(-log(1-P))^k(3)));
end
figure(1)
    plot(T,Q1,'b')
    hold on
    plot(T,Q2,'r')
    plot(T,Q3,'y')
    hold off
    grid
    axis([10^0 10^2 10^4 10^6])
    xlabel('Return period(yr)')
    ylabel('Flood magnitude(cfs)')
    legend('stream 1','stream 2',... 
           'stream3','Location','NorthEast')

end

This is what my code produces, can someone help me so that the y axis will display 10^4 through 10^6 instead of 1*10^5 through 10*10^5

You may notice that the 0 on the y-axis is not there is your screenshot. Because 10^4 to 10^6 is such a wide range, you don't notice that the limits are indeed what you have set them to. You can explicitly show this by calling set(gca,'YScale','log'), or if you are running R2016b or later you can also call xtickformat('%.1e')

The set(gca,'Yscale','log') was exactly what I needed, thanks a lot!
