This is my simple code:

```auto
name_a = df_a[names].unique()[0]
data.add_trace(
    go.Bar(
        x=df_a[xaxis_col],
        y=df_a[yaxis_col],
        name=name_a,
        hovertemplate="%{y:.3s}",
    )
)
data.add_trace(
    go.Scatter(
        x=df_b[xaxis_col],
        y=df_b[yaxis_col]
    )
)
figure = go.Figure(data=data)

```

And i’m getting this graph:

Ok, i got it.  
It’s all becouse i got str on xaxis\_col, not a number
