FAQ
A proportional area chart uses filled regions beneath data lines to represent how values accumulate or divide across a period. The filled area emphasizes volume and proportion, making it easier to compare the relative size of each series at any point along the axis.
Open the tool, add your data points by typing or pasting values, choose the number of series you need, then customize colors, curve style, and legend position. Your chart updates live. When you are happy with it, download or share it directly.
Yes. The core proportional area chart maker is completely free with no sign-up required. You can add multiple series, adjust all display settings, and download your chart as an image at no cost.
A regular area chart overlaps series on the same baseline so you can compare absolute values. A stacked area chart places each series on top of the previous one, so the height of the filled area represents the cumulative total. Both are available in MakeCharts.
CSV and Excel file uploads are available on the Pro plan. On the free plan you can type or paste data directly into the chart editor, and on all plans you can use AI to generate a chart from a plain-language description.
You can choose between linear (straight lines connecting data points) and monotone (smooth, natural-looking curves). Monotone curves are great for continuous data like time series, while linear is cleaner for discrete categories.
Absolutely. Export your proportional area chart as a high-resolution PNG or vector SVG, then drop it into PowerPoint, Keynote, Google Slides, or any design tool. The output is presentation-ready without any post-processing.
Type a description of your data — for example 'monthly sales by region for 2024' — and the AI generates a proportional area chart with series, labels, and colors already configured. You can then edit any detail using the config panel.
