Hello,

I am using Plots.jl to make a histogram. I would like to have control over the bin size, but I can’t seem to find anything specifically saying how to do this in the documentation (or in other posts).

I have an array with all integer values in it, and I would like to create a histogram with bins with a width of exactly 1. I would expect that there is something similar to this that works:

```julia
histogram(my_array, binwidth = 1)

```

Thank you in advance

Maybe this: [How can I get the same bin size for both groups in a histogram? (Julia) - Stack Overflow](https://stackoverflow.com/questions/65783708/how-can-i-get-the-same-bin-size-for-both-groups-in-a-histogram-julia)

Thank you for the link! I managed to make it work for what I need to do. For future reference, something like that works:

```julia
data = rand(0:100, 10000) # 1D Array with data

histogram(data; bins = 0:1:100 ) # Creates the histogram

```

Have you tried the auto-binning algorithms( :sturges, :sqrt, :rice, :scott, :fd) ?  
In your sample “:sqrt”-shows the same histogram

```julia
using Plots
data = rand(0:100, 10000) # 1D Array with data
plot(
histogram(data; bins = 0:1:100 ), # Creates the histogram
histogram(data, bins=:sqrt);
layout=(2,1))

```

That is useful in this specific case, thanks! But I guess I was looking for a more general way to control bin width.

In the" Images"-Packages are two functions “build\_histogram” and “imhist”  
An example with “imhist”
