Frequently asked questions
What is the difference between stacked and 100% stacked?
A stacked bar keeps the real totals — tall bars mean big numbers. A 100% stacked bar rescales every bar to the same height so you compare percentages of a whole.
Do my original values stay intact?
Yes — only the rendering is normalized. Your data grid keeps the original numbers, and the PNG is generated from the normalized view.
Is it free?
Yes — no account, no watermark on standard downloads, everything runs in your browser.
