Hi, how to take value from X axis on Waveform 1 and take value from Y axis of waveform 2 to plot in one waveform? the code?

Exactly what is Waveform 1 and waveform 2? If you plotted them in an axes, you know the x and y signals. For example
subplot(2, 2, 1);
plot(x1, y1);
subplot(2, 2, 2);
plot(x2, y2);
subplot(2, 2, 3);
plot(x1, y2); % Plot y2 using axis of x1.
Or maybe you want to use interp1() to sample y2 at the locations of elements of x1?

I didn't understand that. Are you saying that you have another array, say x1, that says what the x value of each element of waveform1 is?

No No. For waveform1 obtain from workspace (Amplitude=Y-axis) and (Time=X-axis). For waveform2 obtain from decompose wavelet (Detail Coefficient=Y-axis) and (Array sample=X-axis))
Now I want to plot new waveform3 which contains (detail coefficient= Y-axis and Time=X-axis)
