How to Use the Histogram Maker
Enter your numerical data in the text area above, with values separated by commas, spaces, or newlines. You can also paste CSV or spreadsheet data — the tool will automatically detect columns and let you choose which one to plot. Click "Generate Histogram" to create the visualization. Choose between count, percent, or density normalization. Set a custom number of bins or leave it blank for automatic binning. Use the camera icon in the chart toolbar to download your histogram as a PNG image.
What Is a Histogram?
A histogram is a chart that shows the frequency distribution of numerical data. The data is divided into bins (intervals), and the height of each bar represents how many values fall within that bin. Histograms are useful for understanding the shape of your data — whether it's symmetric, skewed, bimodal, or uniform. Unlike bar charts, histograms display continuous data with no gaps between bars.
