How the Histogram Generator Works

From raw values to a finished chart in three simple steps.

1

Enter Your Values

Type, paste, or upload the numeric data you want to visualize. Each row is one observation.

Exam scores: 55, 62, 71, 71, 78, 83, 88, 88, 91, 95 ...

2

Set Bin Size

Choose how many bins to group your data into, or set a fixed bin width. The chart updates live as you adjust.

10 bins for 100 values, or a bin width of 5 for score ranges of 0-100.

3

Customize and Export

Adjust colors, labels, and the statistics panel, then download a high-resolution PNG or SVG.

Blue bars, frequency labels on top, statistics panel showing mean 78 and SD 12.

Histogram Generator — Frequently Asked Questions

What is a histogram and how is it different from a bar chart?

A histogram groups continuous numeric values into ranges called bins and shows how many observations fall in each range. Unlike a bar chart, the bars in a histogram are contiguous — there are no gaps — because the data is continuous. Use a histogram to visualize distributions; use a bar chart to compare separate categories.

How do I use the histogram generator?

Enter your numeric values one per row, set the number of bins or a fixed bin width, and the chart renders instantly. You can then adjust colors, toggle labels and grid lines, enable the statistics panel, and download the result as a PNG or SVG.

How many bins should I use in my histogram?

A common rule of thumb is the square root of the number of data points. For 100 values, 10 bins is a solid starting point. MakeCharts lets you switch between fixed bin count and fixed bin width so you can experiment until the distribution shape is clear.

Is this histogram creator free?

Yes. All chart types including the histogram are free with no sign-up required. You can create, customize, and download histograms at no cost. Pro features like CSV upload and AI fine-tuning are available on paid plans.

Can I create a histogram from a CSV file?

CSV and Excel file upload is available on Pro plans. On the free plan you can paste a column of values directly from any spreadsheet. Either way, the histogram creator handles the binning automatically.
