### <kbd>function</kbd> `bar`

```python theme={null}
bar(
    table: 'wandb.Table',
    label: 'str',
    value: 'str',
    title: 'str' = '',
    split_table: 'bool' = False
) → CustomChart
```

Constructs a bar chart from a wandb.Table of data.

**Args:**

* `table`:  A table containing the data for the bar chart.
* `label`:  The name of the column to use for the labels of each bar.
* `value`:  The name of the column to use for the values of each bar.
* `title`:  The title of the bar chart.
* `split_table`:  Whether the table should be split into a separate section  in the W\&B UI. If `True`, the table will be displayed in a section named  "Custom Chart Tables". Default is `False`.

**Returns:**

* `CustomChart`:  A custom chart object that can be logged to W\&B. To log the  chart, pass it to `wandb.log()`.

**Example:**

```python theme={null}
import random
import wandb

# Generate random data for the table
data = [
    ["car", random.uniform(0, 1)],
    ["bus", random.uniform(0, 1)],
    ["road", random.uniform(0, 1)],
    ["person", random.uniform(0, 1)],
]

# Create a table with the data
table = wandb.Table(data=data, columns=["class", "accuracy"])

# Initialize a W&B run and log the bar plot
with wandb.init(project="bar_chart") as run:
    # Create a bar plot from the table
    bar_plot = wandb.plot.bar(
         table=table,
         label="class",
         value="accuracy",
         title="Object Classification Accuracy",
    )

    # Log the bar chart to W&B
    run.log({"bar_plot": bar_plot})
```
