I’m trying to plot the figure as in [W&B Smoothing Features], but it didn’t provide any code:

Tutorials I could find by searching `wandb multiline in one plot` is [Custom Multi-Line Plots] which introduces `wandb.plot.line_series()`. So I tried the code following

```python
import wandb
import numpy as np

wandb.init(project="test", entity="xxxx")

wandb.log({"my_custom_id":
           wandb.plot.line_series(
               xs=range(100),
               ys=[range(100), np.random.randint(100, size=100)],
               keys=["y1", "y2"],
               title="Multiline",
               xname="steps"
           )})

```

It gives me the following pic after choosing `Edit panel`

Unlike the first picture:

1. It **doesn’t** have `Data`, `Group` etc tabs.
2. There are **two types** of legend `name` and `lineKey` rather than one type.

My question is how to plot exactly the same as the first picture with same function supported in wandb web?

The link is [Example](https://wandb.ai/hoo-leo/example/runs/2q2qigsk?workspace=user-hoo-leo), the corresponding code is in my question.

First I need to log the data I want

```python
import random
import wandb

wandb.init(project="test", entity="xxxx")
for i in range(100):
    wandb.log({"y1": random.random(), "y2": random.random(), "x": i})

```

Then, I need to mannually choosing y1 and y2 on Y Axis.
