Why am I seeing fewer data points than I logged? - Weights & Biases Documentation

When visualizing metrics against an X-axis other than Step, expect to see fewer data points. Metrics must log at the same Step to remain synchronized. Only metrics logged at the same Step are sampled while interpolating between samples. Guidelines Bundle metrics into a single log() call. For example, instead of:

import wandb
with wandb.init() as run:
    run.log({"Precision": precision})
    ...
    run.log({"Recall": recall})

Use:

import wandb
with wandb.init() as run:
    run.log({"Precision": precision, "Recall": recall})

For manual control over the step parameter, synchronize metrics in the code as follows:

with wandb.init() as run:
    step = 100  # Example step value
    # Log Precision and Recall at the same step
    run.log({"Precision": precision, "Recall": recall}, step=step)

Ensure the step value remains the same in both log() calls for the metrics to log under the same step and sample together. The step value must increase monotonically in each call. Otherwise, the step value is ignored.
