Making Sense Of 2 Series At Once
This is a comparison chart, 2 groups at once — the interesting question is usually how the gap between them changes, not the value of any single group in isolation.
Size and growth rate are two different questions here — a series can be small in absolute terms and still be growing the fastest of the group. Check both before drawing a conclusion.
For planning purposes, the end-year figure and the growth rate are the two numbers that matter. Together they show how large the Japan Public Cloud market is projected to become and how quickly it gets there.
This is a market research forecast, not an official statistic. Values after the 2018 base year are modeled projections to 2030, based on supply-side and demand-side analysis, and are updated when market conditions change.
