The parallel coordinates chart shows how hyperparameters relate to metrics across many runs. Each line is one run; each axis is a config key or summary metric. To add a panel, configure axes, colors, and brushes, see Parallel coordinates and Visualize sweep results.

​
Reading the chart

  • Lines that cross between adjacent axes suggest an inverse relationship between those parameters.
  • Lines that run parallel suggest a positive correlation.
  • A tight bundle of lines at a good metric value marks a promising hyperparameter region.
Color lines by a summary metric (for example val/accuracy) so strong runs stand out on a gradient from cool to warm colors.

​
Filtering with brushes

Drag on an axis to brush a value range. Only runs in range stay highlighted. Brushing multiple axes narrows to runs that satisfy all ranges — useful for questions like which learning-rate and batch-size pairs exceed 90% accuracy.

​
Sweeps

After a sweep, filter to the sweep (Filter > Sweep > your-sweep-id) so the panel shows trial runs only. Use the chart to see the explored space and plan a tighter follow-up sweep.
