Frequently Asked Questions
What is a histogram used for?
A histogram is used to summarize discrete or continuous data. It provides a visual interpretation of numerical data organization by indicating the number of data points that lie within a range of values.
How is it different from a bar chart?
Bar charts compare different categories (apple vs orange), while histograms show the distribution of a single numerical variable (ages 20-30, 30-40).
Does it calculate bins automatically?
Yes! Our engine automatically determines the best number of bins (intervals) for your specific dataset.
Can I use negative numbers?
Yes, our tool handles negative numbers, decimals, and large integers seamlessly.
Is my data secure?
Yes, everything runs in your browser. We never see your data.
Can I export the chart?
Yes, once created, you can download your histogram as an image.
