function wandb.plot.line_series()

Constructs a line series chart.

xs: 'Iterable[Iterable[Any]] | Iterable[Any]',
ys: 'Iterable[Iterable[Any]]',
keys: 'Iterable[str] | None' = None,
title: 'str' = '',
xname: 'str' = 'x',
split_table: 'bool' = False

Args

Iterable[Iterable[Any]] | Iterable[Any]

Sequence of x values. If a singular array is provided, all y values are plotted against that x array. If an array of arrays is provided, each y value is plotted against the corresponding x array.

Iterable[Iterable[Any]]

Sequence of y values, where each iterable represents a separate line series.

Iterable[str] | None

Sequence of keys for labeling each line series. If not provided, keys will be automatically generated as “line_1”, “line_2”, etc.

str

Title of the chart.

str

Label for the x-axis.

bool

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().

Examples

Logging a single x array where all y series are plotted against the same x values:

import wandb

# Initialize W&B run
with wandb.init(project="line_series_example") as run:
    # x values shared across all y series
    xs = list(range(10))

    # Multiple y series to plot
    ys = [
        [i for i in range(10)],  # y = x
        [i**2 for i in range(10)],  # y = x^2
        [i**3 for i in range(10)],  # y = x^3
    ]

    # Generate and log the line series chart
    line_series_chart = wandb.plot.line_series(
        xs,
        ys,
        title="title",
        xname="step",
    )
    run.log({"line-series-single-x": line_series_chart})

In this example, a single xs series (shared x-values) is used for all ys series. This results in each y-series being plotted against the same x-values (0-9). Logging multiple x arrays where each y series is plotted against its corresponding x array:

import wandb

# Initialize W&B run
with wandb.init(project="line_series_example") as run:
    # Separate x values for each y series
    xs = [
        [i for i in range(10)],  # x for first series
        [2 * i for i in range(10)],  # x for second series (stretched)
        [3 * i for i in range(10)],  # x for third series (stretched more)
    ]

    # Corresponding y series
    ys = [
        [i for i in range(10)],  # y = x
        [i**2 for i in range(10)],  # y = x^2
        [i**3 for i in range(10)],  # y = x^3
    ]

    # Generate and log the line series chart
    line_series_chart = wandb.plot.line_series(
        xs, ys, title="Multiple X Arrays Example", xname="Step"
    )
    run.log({"line-series-multiple-x": line_series_chart})

In this example, each y series is plotted against its own unique x series. This allows for more flexibility when the x values are not uniform across the data series. Customizing line labels using keys:

import wandb

# Initialize W&B run
with wandb.init(project="line_series_example") as run:
    xs = list(range(10))  # Single x array
    ys = [
        [i for i in range(10)],  # y = x
        [i**2 for i in range(10)],  # y = x^2
        [i**3 for i in range(10)],  # y = x^3
    ]

    # Custom labels for each line
    keys = ["Linear", "Quadratic", "Cubic"]

    # Generate and log the line series chart
    line_series_chart = wandb.plot.line_series(
        xs,
        ys,
        keys=keys,  # Custom keys (line labels)
        title="Custom Line Labels Example",
        xname="Step",
    )
    run.log({"line-series-custom-keys": line_series_chart})

This example shows how to provide custom labels for the lines using the keys argument. The keys will appear in the legend as “Linear”, “Quadratic”, and “Cubic”.
