Quiet histogram events were filling the chart panel even though the
peak was tiny (0.005 in/s rendered as 90% of chart height because
Chart.js auto-scaled to peak * 1.1). Made everything look uniformly
loud regardless of actual amplitude.
BW's solution: a near-fixed scale per channel ("Geo: 0.002 in/s/div"
from the footer). Quiet events render small, loud events render
proportionally tall.
Match the intent without copying BW's "no Y-axis labels at all"
convention. For histogram channels:
Geo (in/s): min Y range 0.05 in/s
Mic in psi: min Y range 0.001 psi
Mic in dBL: unchanged (the 60 dBL floor + peak+5 top already
gives quiet events a sensible baseline)
So a 0.005 in/s geo event renders as ~10% of chart height; a 0.05
event fills it; a 5.0 event still fills it (max(peak*1.1, 0.05) ==
peak*1.1 for any peak > 0.045).
Waveform charts unchanged — they should zoom for shape detail.
Applied to both the modal in sfm_webapp.html and the standalone
/events page in event_browser.html.
