Histogram vs. Pictogram — What's the Difference?
By Tayyaba Rehman — Updated on October 16, 2023
A Histogram is a graphical representation of data distribution using bars of different heights, while a Pictogram uses images or symbols to represent data quantities. Both visualize data but in distinct styles.

Key Differences
Histograms and Pictograms are both tools used to visualize data. The Histogram focuses on representing the frequency of data in intervals using vertical bars, illustrating the distribution. On the contrary, a Pictogram uses images or symbols to represent and convey information about data quantities.
A Histogram is particularly useful for showcasing the distribution of continuous or numerical data over a set of intervals or bins. Each bar's height indicates the number of data points in that interval. Pictograms, however, might depict the number of occurrences using a specific image, where one image might represent ten, hundred, or any other quantity of occurrences.
In a Histogram, the width of each bar represents an interval, and there are no gaps between bars unless there's no data for a specific interval. Pictograms don't have such stringent rules about representation. Instead, they use pictures or symbols creatively to make data more understandable, relatable, and often more appealing to a broader audience.
When it comes to precision and analysis, Histograms tend to be more accurate as they can provide a clearer view of data distribution, making it easier to interpret. Pictograms, while engaging and easy to understand at a glance, might sometimes sacrifice precision for aesthetics or simplicity.
Both Histogram and Pictogram serve the purpose of data visualization. While Histograms might be more commonly found in statistical analyses or research reports, Pictograms can be seen in public information campaigns, infographics, or educational contexts, due to their illustrative and intuitive nature.

Histogram
A tool for understanding data distribution.
Researchers often use Histograms to identify patterns.
Pictogram
A graphical representation often used for easy understanding.
Children's books may use Pictograms for teaching numbers.
Histogram
A graph representing data distribution.
The Histogram showed a bell-curve distribution.

Uses pictures to represent data quantities.
The Pictogram used apples to represent the number of fruits sold.
Histogram
Uses vertical bars to denote frequency.
The taller bars in the Histogram indicated higher data frequency.

The health campaign used a Pictogram to show the benefits of eating greens.
Histogram
Visualizes data over set intervals or bins.
The Histogram divided data into ten equal bins.
Pictogram
Makes data relatable using intuitive symbols.
The Pictogram about global warming used icebergs to convey melting rates.
Histogram
Bars are contiguous unless no data for an interval.

Histogram
A histogram is an approximate representation of the distribution of numerical data. The term was first introduced by Karl Pearson.
Pictogram
Prioritizes visual appeal and simplicity.
The colorful Pictogram was both informative and engaging.
Histogram
A bar graph of a frequency distribution in which one axis lists each unique value (or range of continuous values) in a set of data, and the area of each bar represents the frequency (or relative frequency) of that value (or range of continuous values).
Pictogram
A pictogram, also called a pictogramme, pictograph, or simply picto, and in computer usage an icon, is a graphic symbol that conveys its meaning through its pictorial resemblance to a physical object. Pictographs are often used in writing and graphic systems in which the characters are to a considerable extent pictorial in appearance.
Histogram
(statistics) A graphical display of numerical data in the form of upright bars, with the area of each bar representing frequency.
Pictogram
A picture that represents a word or an idea by illustration.
Histogram
(transitive) To represent (data) as a histogram.
Histogram
A bar chart representing a frequency distribution; heights of the bars represent observed frequencies
Common Curiosities
