Suppose I have two functions, say y = sin(t) and y = sin( t + pi/4) and I want to make them start at the same point. How can this be done?
MATLAB: Two functions superimposed on each other.

t = linspace(0,10) ;s = sin(0.5)*sin(2*pi*900*t+2*pi/3) ;plot(t,s)It is difficult to give exact solution without the exact data. But, below is an example of how you can superimpose 2 data using imagesc with different transparency & colormap.
%plot first data
ax1 = axes; im = imagesc(ax1,imread('cameraman_512.png')); im.AlphaData = 0.5; % change this value to change the background image transparency
axis square; hold all; %plot second data
ax2 = axes; im1 = imagesc(ax2,imread('fighter.png')); im1.AlphaData = 0.5; % change this value to change the foreground image transparency
axis square; %link axes
linkaxes([ax1,ax2]) %%Hide the top axes
ax2.Visible = 'off'; ax2.XTick = []; ax2.YTick = []; %add differenct colormap to different data if you wish
colormap(ax1,'summer') colormap(ax2,'winter') %set the axes and colorbar position
set([ax1,ax2],'Position',[.17 .11 .685 .815]); cb1 = colorbar(ax1,'Position',[.05 .11 .0675 .815]); cb2 = colorbar(ax2,'Position',[.88 .11 .0675 .815]);
