metrics-chart

Turns a metrics query response into a multi-series line chart.

Input is a saved {metadata, series} response in metrics v2 or v3 format. For MCP results, call queryMetrics with truncate: false and save its structuredContent as the input JSON. The default CSV preview can omit series and samples.

TL;DR

# From a file, stdout picks the best renderer for your terminal:
python3 scripts/metrics_chart.py response.json

# Read the same saved response from stdin:
python3 scripts/metrics_chart.py < response.json

# Force a zero-dependency ASCII chart (always works, anywhere):
python3 scripts/metrics_chart.py --format ascii response.json
