Frequently Asked Questions
How is a histogram different from a bar chart?
Bar charts display discrete categorical groups, whereas histograms show the frequency distribution of continuous numerical data grouped into equal-width bins.
Can I adjust the number of bins?
Yes! Use the Histogram Bins slider in Chart Settings to adjust between 3 and 30 frequency bins.
Can I download the histogram as vector SVG?
Yes, export vector SVG files for crisp scaling in academic papers and reports.
