I am creating a bar plot that shows relative contributions on a per row basis, such as this:

```auto
import pandas as pd
import plotly.express as px

d = pd.DataFrame({'a': [3,4,7], 'b': [5,4,1]})

fig = px.bar(d, x=d.index, y=['a','b'])
fig.show()

```

 ![pxbar](https://us1.discourse-cdn.com/flex024/uploads/plot/original/3X/f/1/f1f172a5aa908d139901049b3b1408465555a5cb.png)

When I try to put this into a subplot by adding the plotly express traces, the bars are no longer stacked:

```auto
import pandas as pd
import plotly.express as px
from plotly.subplots import make_subplots

d = pd.DataFrame({'a': [3,4,7], 'b': [5,4,1]})

fig = px.bar(d, x=d.index, y=['a','b'])

fig2 = make_subplots(2,2)
fig2.add_traces(list(fig.select_traces()), rows=1, cols=1)
fig2.show()

```

Any suggestions on how to reproduce the plotly express behavior within the subplot would be appreciated.

Thank you - Marie

The solution to this is to set the barmode of the subplot figure to relative:

```auto
fig2 = make_subplots(2,2)
fig2['layout'].barmode ='relative'
fig2.add_traces(list(fig.select_traces()), rows=1, cols=1)

fig2.show()

```
