Why would you not just ask for the axis handle and skip the plot section? Then the user could plot whatever he wants, however he wants, and then apply the axes at origin? Then you could for example also preserve x-and ylabels (or rewrite them)

Hello, I´m not really familar with Matlab but can somebody tell me how to use this file ? Matlb gives me this Error note:

Error: Function definitions are not permitted in this context.


Dear Shanrong Zhang,

please add output H=PlotAxisAtOrigin(x,y),
along with a slight change in the second active line: H=plot(x,y);

It allows handling of the figure:
function H=PlotAxisAtOrigin(x,y)
% Example:
% x = -2*pi:pi/10:2*pi;
% y1 = sin(x);
% y2 = cos(x);
% y = [y1;y2];
% H=PlotAxisAtOrigin(x,y);
% H(1).LineWidth = 3;
% H(2).Marker = '*';
% H(2).Color = 'm';

if nargin == 2
%--contunue as in your original code ----

works just as needed. Thank a lot!

when x and y doesn't contain zero , for example x=5:0.1:10; y=2*x . the function will not work

- Hide in comment line containing set(gcf,'color','w')

@Markus Buehren:
- It doesn't work because "Axes in origin" are actually lines in regular axes, which are hidden.

I'm thinking of writing function AxesToOrigin based on this function...

Great function!
2 comments though:
-I don't like that it changes the background color.
-I wish it wouldn't need to take any arguments.

Hello, I can not understand how to apply this to my code. I want to shift the current origin to (0,0) from (-0.3, 0) but the -y axis should not appear. My code is:

% 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')


set(gca,'XTickLabel',{'-0.3','-0.2','-0.1','0','0.1', '0.2', '0.3'})

ylim([0 90]);
xlim([-0.3 0.3]);

title('BED Plots for Organs');
xlabel('Epsilon range of alpha/beta');

%Thank you very much!

Hi this is great but what do I do if I want to add axis labels?

I tried it. Works fine for me. Exactly what I wanted. Thanks for sharing

Sorry, but I think this package is not very useful. On the first view it looks nice, but the axis will not change when zooming in etc.
