# wandb.data\_types.Histogram

[![](https://www.tensorflow.org/images/GitHub-Mark-32px.png)View source on GitHub](https://www.github.com/wandb/client/tree/v0.10.31.dev1/wandb/sdk/data_types.py#L265-L342)

wandb class for histograms.

```python
Histogram(
    sequence: Optional[Sequence] = None,
    np_histogram: Optional['NumpyHistogram'] = None,
    num_bins: int = 64
) -> None
```

This object works just like numpy's histogram function <https://docs.scipy.org/doc/numpy/reference/generated/numpy.histogram.html>

## Examples:

Generate histogram from a sequence

```python
wandb.Histogram([1,2,3])
```

Efficiently initialize from np.histogram.

```python
hist = np.histogram(data)
wandb.Histogram(np_histogram=hist)
```
