Bar charts have spaces between each category. The action you just performed triggered the security solution. The major difference between a histogram and a bar chart is the bars of the bar chart are not just next to each other. The area of each bar is the same as its respective frequency when intervals are unequal. A histogram is used to check the shape of the data distribution. By using our site, you A histogram is a visual representation of data, a two-dimension graph that uses a set of vertical rectangles(emphasizing both the lengths and widths of the rectangles) to represent class frequencies of the given distribution. Used to analyze whether the given process meets the customers requirements. To draw a vertical histogram, we choose the height of students(class intervals) for the $x$-axis and the number of students(frequency) for the $y$-axis. The plot is made up of bars that are placed alongside each other. In a histogram, the bars are adjacent to each other. This involves predicting trends and making data-driven decisions.

Solution: The fundamental difference between histograms and bar graphs from a visual aspect is that the bars in a bar graph are not adjacent to each other. by The ranges are split based on the specified bin value. Bar charts are used to show comparisons between different groups or categories, while histograms are used to show the distribution of data. One such widely used graphical representation of data is the histogram. The length of each bar corresponds to its respective data mentioned on the axis (Y-axis for Vertical Graph, X-axis for Horizontal Graph). For example, the following histogram shows the marks obtained by the 48 students of Class 8 of St.Marys School. The width and spacing between the bars are maintained equally. The following histogram displays the number of books on the x -axis and the frequency on the y -axis. It depends on the data you have and what you want to show with it.
