On x_axis I have different 128 channels. On left y_axis I have input signal and on right y_axis I have colorbars corresponding to output data. Actually output is represented as color information.

You can obtain something similar using pcolor(). For Example
[x, y] = meshgrid(1:128, 0:70); % 2d meshgrid
z = sort(rand(size(x))); % sample data, use your own variable
p = pcolor(x,y,z);
p.EdgeAlpha = 0;
colorbar;
I am using random data points therefore it does not look the same as your image. Note that to display white color on the plot, the corresponding element in z variable must be inf.
