pulsatrix::AttributionWaterfallChart Class Reference

Draws a waterfall chart cascading from baseline_value to the final prediction (hc_information_visualization.md SS5: "correct for local explanation with directional attribution... bars cascade from base rate to prediction; color encodes direction; length encodes magnitude"). This is the one bar chart in this module that legitimately does not start at zero – Tufte's lie-factor rule is satisfied relative to baseline_value, the meaningful reference point, not zero. More...

Detailed Description

Draws a waterfall chart cascading from baseline_value to the final prediction (hc_information_visualization.md SS5: "correct for local explanation with directional attribution... bars cascade from base rate to prediction; color encodes direction; length encodes magnitude"). This is the one bar chart in this module that legitimately does not start at zero – Tufte's lie-factor rule is satisfied relative to baseline_value, the meaningful reference point, not zero.

Note

Deliberately not unit-tested – see AttributionBarChart's note. All real logic (cumulative computation) lives in plot_data.hpp's ToWaterfallSteps, which is.
