### 🐞 Description of the bug

Two bug in Plots and Graphics
## Plots
Execute the code from `https://developer.ansys.com/blog/pythonic-interface-ansys-fluent` as follow:
```
I just got a sketch and warning in jupyter notebook.
2023-08-15 11:09:29,541 matplotlib.legend WARNING No artists with labels found to put in legend. Note that artists whose label start with an underscore are ignored when legend() is called with no argument.
```


## Graphics
I found something strange:
The contour was filled at the first time, as the example code.
```
temperature_contour = graphics.Contours["contour-temperature"]
temperature_contour.field = "temperature"
temperature_contour.surfaces_list = ["mid-plane-x",]
temperature_contour.display()
```

however, in my custom class, I have a function refer to the code:
```
def contour(self,contour_name:str,field:str,filled=True,surfaces_list:list=None):
con=self.graphics.Contours[contour_name]
# con.field.allowed_values
con.field=field
# con.filled=filled
# con.surfaces_list.allowed_values
con.surfaces_list=surfaces_list
con.display(contour_name)
```
the contour is not filled, even if add the `con.filled=filled`.


I have tried many times, occasionally it works a few times by 'con.filled=True'
