Hi @noureddiuno,

The reason you’re getting the deprecation warning is the use of the `Data`, `Stream`, `YAxis`, and `Marker` classes from:

```python
from plotly.graph_objs import Scatter, Layout, Figure, Data, Stream, YAxis, Marker

```

These should be replaced by the classes suggested by the deprecation warnings.

Thank you @jmmease for your fast reponse,

I made some changes in libs import, it soved part of problem but “from plotly.graph\_objs import Data” still shows warnning !!

I don’t inderstand why my programs ran very well before 25 october 2018 (without any of previous warnnigs) ?

yours sincerely.

Hi @noureddiuno,

The deprecation warnings starting in version 3.0. The `plotly.graph_objs.Data` class is no longer needed. It should be replaced with a simple `list` or `tuple`.

So change

```python
data = Data([temp11])

```

to

```python

data = [temp11]

```

Hope that helps,  
-Jon
