Why is the contour different when a) manually taking the log10 of the data vs b) using options like 'XScale','log'?

Hi there,
I am plotting contours in MATLAB and noticed that the contours look different when I:
- Manually take the logarithm of both x and y data
figure
contour(log10(x),log10(y),INR1,[1,1],'Color','r','LineWidth',1.2)
hold on
contour(log10(x),log10(y),INR2,[3.6,3.6],'Color','b','LineWidth',1.2)
- Use the XScale and YScale options
figure
contour(x,y,INR1,[1,1],'Color','r','LineWidth',1.2)
hold on
contour(x,y,INR2,[3.6,3.6],'Color','b','LineWidth',1.2)
set(gca,'FontSize',18,'XScale','log','YScale','log')
I am not too sure what have I done wrong here. Please let me know if you have any ideas. Thank you in advance!
