How do I shift ONLY the y axis in a plot?

Hello,

I want to create a graph where y runs from 0 to 500 with intervals of 20 and x runs from -0.3 to 0.3 with intervals of 0.1 each. I have written the following code which plots the graph:

% Plot for lambda = 0.5

n = 30;

dc1 = 1/30*(0.5*66+0.5*62);
dc2 = 1/30*(0.5*57+0.5*55);

dn1 = 1/30*(0.5*40+0.5*30);
dn2 = 1/30*(0.5*35+0.5*20);
dn3 = 1/30*(0.5*20+0.5*27);

e = -0.3:0.01:0.3;

bc1 = 30*dc1*(1+(dc1./(10+e)));
bc2 = 30*dc2*(1+(dc2./(10+e)));

bn1 = 30*dn1*(1+(dn1./(2+e)));
bn2 = 30*dn2*(1+(dn2./(2+e)));
bn3 = 30*dn3*(1+(dn3./(2+e)));

    plot(e, bc1, 'g')
    hold all
     plot(e, bc2, 'r')
     hold all
     plot(e, bn1, 'b')
     hold all
     plot(e, bn2, 'y')
     hold all
     plot(e, bn3, 'black')

When I run this, a normal graph with the y axis at the left appears. What should I add to the code so that I can shift only the y axis at (0,0)such that (1) there's no change in the x axis, (2) no negative y axis appears.

Thank you!

Did you try:

ylim([0 500])

[Sam]

ylim([0 500]) changes the limit of y from 0 to 400, but the y axis is still on the left side of the graph. I want the y axis to shift to the center(so that the origin becomes (0,0) instead of (-0.4,0) as it is now.

try this ax.YAxisLocation = 'origin'

Hello

I am unable to use the file to shift my axis to the center. When I add PlotAxisAtOrigin(0,0); the y axis disappears completely. I am quite new at Matlab, I will be grateful if you could help me by telling me how to run the file.

Thank you.
