Bar Charts And Histograms. In Bar graphs the length of the bars shows the frequency but the width has no special significance but in Histograms the frequency is shown by the area of the bar. Rather than showing every single age a group might be maybe you just show people from 20-25 25-30. Histograms can have unequal bar widths. Histograms can have unequal bar widths if the bin intervals differ.
Difference Between Histograms and Bar graph. Bar graph is a one-dimensional figure while Histogram is a two-dimensional figure. A histogram represents the frequency distribution of continuous variables. A bar graph is a pictorial representation of data that uses bars to compare different categories of data. Rather than showing every single age a group might be maybe you just show people from 20-25 25-30. The Histogram refers to a graphical representation that shows data by way of bars to display the frequency of numerical data whereas the Bar graph is a graphical representation of data that uses bars to compare different categories of data.

Rather than showing every single age a group might be maybe you just show people from 20-25 25-30. Bar graphs and histograms look similar and people often use the terms interchangeably but they are not the same kind of graph. The area of each bar in a histogram should be proportional to the data. Histograms can have unequal bar widths if the bin intervals differ. Bar charts have equal widths. Examples of this might be age groups or scores on a test.
