NULL_STRING : String(value); Review Comment: This uses the display placeholder as the lookup key, so a database NULL and a literal "<NULL>" category or series value collide. The Set/Map then discards one candle rather than rendering both. Could the internal key use a distinct null sentinel and only format the placeholder for display? -- This is an automated message from the Apache Git Service.
