Histogram Maker

A histogram groups continuous data into bins and plots the count in each. The horizontal axis carries the measured variable divided into equal intervals, the vertical axis carries frequency, and the bars touch because the underlying scale is continuous. SciFig's histogram maker builds this layout for you with the axes already labeled.

A histogram shows continuous data; a bar chart shows categories. Because a histogram's intervals are adjacent parts of one numeric scale, its bars have no gaps, while a bar chart separates its bars to signal that the categories are unrelated. Using the wrong one is a common figure error in submitted manuscripts.

Start near the square root of your sample size, then adjust. Too few bins hide structure such as a second peak; too many turn the distribution into noise. A histogram creator makes this cheap to test — regenerate with a different bin width and keep whichever version shows the shape most honestly.

Describe your variable, units, and bin width, and generate the figure. SciFig's histogram maker outputs a chart at publication resolution with axis titles, units, and readable tick labels already in place, so it can go straight into a manuscript or a poster panel without further formatting.

The shape reveals the distribution behind your measurements. A symmetric bell suggests a normal distribution, a long right tail indicates positive skew, and two peaks suggest a mixed population worth separating. A histogram generator lets you check that shape before choosing a statistical test that assumes normality.

Yes — you can generate a histogram in the browser with no install. SciFig works as an online histogram maker: describe the distribution you need, generate the figure, then refine labels and export. Free credits cover your first charts, and every export stays editable rather than locked to a template.
