Adding text to y-axis - MATLAB

问题

I have a plot and I would like to add on the y-axis the values of 1σ, 2σ, 3σ etc. instead of numbers assigned by MATLAB. However, the x-axis remains as normal. Is there any way to do this?

Thanks

Changing the tick labels is easy, as you can see from the following example.

x = 0:pi/500:2*pi;
y = sin(x);
plot(y, x);
set(gca, 'YTick', [0 pi/2 pi 1.5*pi 2*pi]);
set(gca, 'YTickLabel', {'0', 'pi/2', 'pi', '3/2 pi', '2 pi'});

However, the (la)tex interpreter is still unsupported and hence you should consider to replace the labels with text objects.
