a multiplicative decomposition of '{col}' meets a non-positive value, where the ratio value ÷ trend is undefined; those rows report null. Use the additive model for a series that crosses or sits at zero.

What happened

A multiplicative decomposition divides by the trend, which is meaningless at or below zero. The rows at fault report null - the rest of the series is decomposed normally - so the column has gaps where the values touch zero.

The fix

Use the additive model for a series that crosses or sits at zero.

The smallest fix

decompose: { of: 'balance', period: 12, model: 'additive' }
