Thanks for taking the time to further explain your use case.

You are right that you cannot pass an `xbins` attribute directly to the `px.histogram` constructor.

This is because Plotly Express was designed as a terse, high-level wrapper for the `graph_objects` library, so only a subset of the attributes that you can set using a `graph_objects` constructor are available in the Plotly Express constructors for figures.

However, it is important to note that the Plotly Express constructor always returns a `graph_objects` figure object.

This means you can use the `update_traces` method to set any attributes which are available on the figure after using the Plotly Express constructor.

```python
import plotly.express as px
df = px.data.tips()
fig = px.histogram(df, x="total_bill")

fig.update_traces(xbins=dict( # bins used for histogram
        start=0.0,
        end=60.0,
        size=2
    ))

fig.show()

```

I hope that answers your question.
