 All plotting and analysis scripts use the JSON export's `primary_metric` by default.
-Pass `--metric` to select a different metric. Supported metrics are `time_wall_clock`,
-`time_cpu`, `time_user`, `time_system`, `memory_peak_resident`, `cpu_cycles`,
-`instructions`, `cache_references`, `cache_misses`, and `branch_misses`, provided the
-selected metric is available in every benchmark being analyzed. For example:
 
 ```bash
 uv run plot_histogram.py benchmark.json --metric instructions
 ```
 
-Time is displayed in seconds, memory in MiB, and counters as unscaled counts.
-Multi-file plots require matching primary metrics unless `--metric` explicitly selects
-one metric across all files. Exports without `primary_metric` fall back to wall-clock
-time; the per-run `measurements` JSON schema is still required.
-
-For descriptive statistics or a Welch's t-test comparing exactly two benchmark results:
-
-```bash
-uv run advanced_statistics.py benchmark.json --metric time_cpu --time-unit millisecond
-uv run welch_ttest.py comparison.json --metric memory_peak_resident
-```
-
-`advanced_statistics.py` accepts `--time-unit second` or `--time-unit millisecond`
-for time metrics only. Both analysis scripts also accept the default primary metric
-without `--metric`.
