I am trying to use `ax.hist(vector1d, 20, density=0)`

to plot the histogram, where the vector1d is a tensor of decimals in the level of 1e-13, i.e.,

```
>>> one_batch_error_grad
tensor([-1.3246e-13, -1.0851e-13, -1.0851e-13, ..., 5.2838e-14,
4.4859e-14, -3.1314e-14])
```

But I got the histogram as below, since like the `ax.hist()`

cannot deal with small decimal numbers? I have used it for

Is it because of the version? I am using matplotlib==3.3.2
