The main difference between bar graphs and histograms are given below:

- A
**bar graph**is the graphical design of categorical data managing rectangular bars where the width of the individual bar is equivalent to the value they describe. - A
**histogram**is the graphical description of data wherever data is bunched into continuous number ranges and each range compares to a perpendicular bar.

In the bar graph, there is equal space among every two continuous bars. | In the histogram no space separating two progressive bars. They should be joined to each other. |

The x-axis can describe anything. | The x-axis should serve only consecutive data that is in words of digits. |
