When using `histogram()`, specifying a number of bins with the input argument `nbins` isn't working. ``` rng(1) x = randn(100,1); nbins = 5; histogram(x,nbins) fig2plotly(); ``` The previous code should plot a histogram with 5 bins, however, it plots it with many more. This leads to differences in each bin's width and value.
