FAQ

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.

How do I share or embed my stacked area chart?

Click 'Share' to copy a direct link to your chart. Plus and Pro users can also copy an embed code to display a live chart on any website or blog. All users can download a PNG or SVG for offline sharing.

Can AI generate a 100% stacked area chart for me?

Yes. Describe your data in plain language — for example, 'show quarterly revenue share by product line for 2024' — and the AI builds a ready stacked area chart. Every account includes free AI credits to try this feature.

What types of data work best in a 100% stacked area chart?

This chart type works best with time-series data where you have multiple categories that together form a meaningful whole — such as market share, budget allocation, traffic source mix, or demographic proportions. Avoid it when absolute values matter more than relative share.

Is there a limit to how many series I can add?

There is no hard series limit in the editor, but readability typically drops beyond six to eight series. For dense data, consider grouping smaller categories into an 'Other' series to keep the chart clear.

Do I need to normalize my data before using the 100% stacked area chart maker?

No. Enter your raw values and the chart maker converts them to percentages automatically. You can focus on the data story instead of manual calculations.
