Give appropriate xlim and ylim to make sure the curve is in the sourtheast. But, actually, I am not sure what you want.

thank you for your answer. I do not know how to attach a picture, or else I will draw a draft. you can enter the order 'axis ij', then you will see my meaning. If you make the calibration of x-axis to the top, it is the fig that I want.

set(gca,'xaxislocation','top')
