Stacked area chart · 2026

A revenue analyst generated daily hotel occupancy metrics to automate reporting from raw reservation data. The top chart is a line chart tracking rooms occupied from July 2015 through late 2017, showing a volatile daily occupancy line fluctuating between roughly 50 and 400 rooms, overlaid with a smoother 30-day rolling average. The middle chart is a stacked area chart breaking down the total occupancy, where a Resort Hotel maintains a relatively stable baseline just under 200 rooms during peak seasons, while a City Hotel accounts for the remaining volume and drives much of the overall volatility. A calendar heatmap uses a purple color scale to represent room counts up to 400.

What it shows:

How to manually expand individual booking date ranges into a continuous time series.
