Hi everyone,

I created a linear plot with plotly.py.  
Below is my code :

```
import plotly.express as px

fig = px.area(df_CO2_regions, x="year", y="co2_billions_t", color="country",
              labels={'co2_billions_t':'CO2 billions tonnes'})

fig.update_layout(height=500, width=1300, title_text="CO2 emissions by region", title_x = 0.5)

fig.show()

```

and this the plot

 ![Capture d’écran 2020-10-31 à 16.27.59](https://us1.discourse-cdn.com/flex024/uploads/plot/original/2X/b/b1fea0f4826003671f144a4cfc463604197442bd.png)

In the legend of the colors i would like to delete the word country for each line and write it juste for the title of the legend. Also i would like to show more dates on the x axis.  
Can someone know how to do that ?

Thank you

Hi @tati, Yes, you should be able to do something like:

```python
import plotly.express as px

fig = px.area(df_CO2_regions, x="year", y="co2_billions_t", color="country",
              labels={'co2_billions_t':'CO2 billions tonnes'})

fig.update_layout(height=500, width=1300, title_text="CO2 emissions by region", title_x = 0.5)

for tr in fig.select_traces():
    tr['name'] = tr['name'].replace('country = ','')

fig.show()

```

To add more dates, you can put this after `fig = px.area...`

```python
fig.update_xaxes(nticks=20)

```

Say if you want 20 dates.
