I get an error every time I try plotting in Julia. The code I have been using to generate the histograms is as below:

```julia
using StatsBase

using Plots

a = reshape(intl,(500*100)) ;

plt1 = fit(Histogram,a,30:10:150) ;

plot(plt1,xticks=30:10:150,xlim(30,150)) ;

```

The error is as follows:

What package versions are you using (use `]st` to get package status)? Your code works for me. Note that the semicolons are unnecessary in Julia:

```julia
using Plots, StatsBase
hist_data = vec(rand(30:1:150, 500, 100))
plot(fit(Histogram, hist_data, 30:10:150), xticks=30:10:150, xlim=(30, 150))

```

I tried running your code and get the same error mentioned earlier. This is the output I get on using `]st`

1. Update your packages and `]build`; there’s a more recent release of `Plots.jl` that may fix your issue
2. Try a simpler plot, e.g. `plot(1:10)`: the histogram recipe might be broken
3. Switch backends: first `]add GR`, then `using Plots; gr()`

It looks as if something is wrong in your pyplot installation - changing the backend to gr should solve it.  
Try to plot something with pyplot (without using Plots) - if that fails too you might open an issue on the pyplot repo.

you are working on which version?
