History charts show recorded points only
A sparse history chart does not mean the price changed only a few times. It means the dataset currently has only a few stored observations for that product, country, plan, and currency view.
SubscriptionCompare avoids filling missing periods with fake values. If there is no recorded point, the chart leaves that gap out instead of inventing a trend.
A flat line still needs context
A flat converted price can mean the local price and exchange rate were both stable, or it can mean there are only a few observations. The record count and source date help readers judge how much confidence to place in a chart.
For decisions that depend on current pricing, history should support the source check, not replace it.
What history is best for
History is best for spotting whether a country is consistently low, whether a listed value is new, or whether a price has changed recently.
It is not designed to forecast future subscription prices. Providers can update prices, taxes, and plan structures without following a predictable pattern.
