Automatically group raw data into beautiful frequency distribution charts
How large should each group be? (e.g. A size of 10 groups data into 60-70, 70-80, etc.)
Paste a massive list of unorganized numbers below. You do not need to count or sort them!
Format: Separate your numbers by commas OR spaces OR new lines.
What we do
Easily create professional frequency distribution charts. Histograms are the gold standard for visualizing how data spreads across different ranges (like age or test scores).
Never sort data manually again! Simply dump your raw unorganized numbers into our parser, and our engine mathematically sorts, groups, and counts the frequencies for you.
Need groups of 5 instead of groups of 10? Just type a new number in the "Bin Size" box and watch the entire chart mathematically redraw itself in real-time.
Unlike standard bar charts, true histograms represent continuous data and shouldn't have gaps. Our engine forces the bars to 100% width, locking them side-by-side perfectly.
Make your analysis instantly readable. Hover over any thick bin to see the exact range (e.g. 70 - 80) and the precise number of entries that fell into that category.
Your statistical data is completely private. Because our rendering engine runs natively inside your browser, your raw numbers are never uploaded or stored on any server.
