I have a vector of binary elements and I form another vector of the same length by mapping
{0,1} --> {1,-1}
respectively. White Gaussian Noise is added to this vector and by the property of random vectors, this vector, now say R, is also a random vector. Is there a way to plot the distribution of this vector R other than the histogram method?

Thank you! This helped me. I had to plot the evolution of my pdf over iterations and histogram didn't help me in that case. Thanks again!

See if the ecdf (link) function and related functions such as ecdfhist (link) will do what you want.

Thanks for the help! The command plots the Cumulative Density Function of my data. I have to plot the evolution of pdf over time and this command might help me check if my pdf is correct. Appreciate it!
