Hi
What can I do to prevent plotting new figure and my new data be plotted on previous figure? (I’m using Jupyter Notebook)
```auto
import plotly.graph_objects as go
fig = go.FigureWidget();
fig.add_trace(go.Bar(x=[1, 2, 3], y=[1, 3, 2]));
fig.show();
fig.update_traces(go.Bar(x=[4, 1, 6], y=[2, 5, 4]));
fig.show();
```
This is what I get, But I want only the first plot remain and get updated and prevent plotting new figure! (I’m using Jupyter Notebook)

Hi,
You can just remove the first `fig.show()`.

Hi @jlfsjunior
But in this case, the first figure data won’t update and the initial data remains on the figure!
It is important for me that figure data can become update after `Fig.show()` command. imagine I have a loop and in each loop I have new data:
```auto
import plotly.graph_objects as go
import random as rnd
fig = go.FigureWidget();
fig.add_trace(go.Bar(x=[1, 2, 3], y=[1, 3, 2]));
fig.show()
for i in range(10):
fig.update_traces(go.Bar(x=[rnd.random()*10, 1, 6], y=[2, 5, 4]));
```

Sorry, replied too fast… I don’t think the data can be updated via `update_traces`…
You can try this instead:
```nohighlight
fig = go.FigureWidget();
fig.add_trace(go.Bar(x=[1, 2, 3], y=[1, 3, 2]));
fig.data[0].x = [4, 1, 6]
fig.data[0].y = [2, 5, 4]
```

@jlfsjunior
Thanks for your contribution and guidance
I wrote this according your guidance:
```auto
import plotly.graph_objects as go
fig = go.FigureWidget();
fig.add_trace(go.Bar(x=[1, 2, 3], y=[1, 3, 2]));
fig.show();
fig.data[0].x = [4, 1, 6]
fig.data[0].y = [2, 5, 4]
```
But the figure didn’t update and the initial data remains. what is my mistake?

I am not super familiar with FigureWidget, but maybe `fig.show()` doesn’t allow for updates… The solution [here](https://community.plotly.com/t/unable-to-update-data-keep-creating-new-one-instead/29696/2) doesn’t use it, for instance…
Another alternative is to go with a “full-fledged” widget, as described [here](https://plotly.com/python/v3/figurewidget-app/).

Dude @jlfsjunior
You helped me. I found the answer by your great help: 👍 🙏
```auto
import plotly.graph_objects as go
import random as rnd
fig = go.FigureWidget();
fig.add_trace(go.Bar(x=[1, 2, 3], y=[1, 3, 2]));
display(fig)
for i in range(10):
fig.data[0].x = [rnd.random(), 1, 6]
fig.data[0].y = [rnd.random(), 5, 4]
```
