How can l choose the number of bins to plot a histogram for gibbs sampling process?

[Ahmed Mazari]

Hello,

l want to plot a histogram for gibbs sampling distribution. But l don't  know how to choose the number of bins !!

x is the set of all possible values

y the frequency of each x value.

What should be the appropriate number of bins ?

Thank you

There are lots of packages that are capable of doing plotting in Julia already Gadfly, Plots, etc. which are all capable of doing histograms. If you are set on calculating the bins and widths yourself and making your own function to plot the histogram I suggest you read through the wiki article on histograms, they have an excellent section on many different rules for selecting bin sizes and widths.
