Frequently Asked Questions
What is a 100% stacked area chart?
A 100% stacked area chart displays multiple data series as layers that together always fill 100% of the chart height at every point on the x-axis. Unlike a regular stacked area chart, it shows the relative proportion of each category rather than absolute values. This makes it ideal for comparing how the mix of categories changes over time.
How do I make a 100% stacked area chart for free?
Open the MakeCharts 100% Stacked Area Chart Maker, add your data series and values, and the chart normalizes everything to 100% automatically. No sign-up is required. Download your finished chart as a PNG image at no cost.
Can I upload a CSV file to create a stacked area chart?
Yes. Pro plan users can upload a CSV or Excel file and the tool maps columns to series automatically. Free and Starter users can paste data from any spreadsheet directly into the editor.
What is the difference between a stacked area chart and a 100% stacked area chart?
A regular stacked area chart shows absolute cumulative values, so the top of the chart varies with the total. A 100% stacked area chart normalizes every data point so the chart always reaches 100%, emphasizing proportion rather than volume. Use the 100% version when relative share matters more than the size of the total.
Can I customize the colors and curves in my area chart?
Yes. Each series has its own color picker and stroke width control. You can also switch between smooth monotone curves and straight linear segments to match your data and style preferences.
