histogram (VCM Scanner)

A VCM Scanner analysis tool that bins logged data into a table-shaped grid (matching a tune table's axes) and averages each cell.

A histogram in VCM Scanner organizes logged data into a grid whose axes mirror an Editor table (for example RPM vs cylinder airmass, or RPM vs MAP). As data streams in, each sample drops into the matching cell and the histogram displays the average, count, or other statistic for that cell. This is the backbone of data-driven tuning: you build a fuel-trim or knock histogram shaped like the VE/airflow table, log a drive, and then use the per-cell results to correct the corresponding cells in VCM Editor. It turns thousands of raw samples into actionable, table-aligned corrections instead of guesswork. Cell count matters for trust, so a cell with only a couple of hits is statistically weak and shouldn't drive a big change. You configure histograms in Scanner's layout (choosing the parameter, axes, and breakpoints, ideally matching your Editor table exactly), and they update live and over recorded logs.
