A histogram is one kind of bar chart.
Bar charts
If we want to represent the data collected about qualitative variable then a bar chart is the simplest method to employ.
The gaps between the categories in a bar chart are important: they emphasise the fact the categories used are mutually exclusive and do not form a continuum.
Histograms
Like bar charts, a histogram is produced by sorting data into categories (called bins). However, unlike a bar chart, the values on the x-axis form a continuum: the point at which one bin ends is the point at which the next bin begins. For this reason, neighbouring bars in a histogram must touch. In a bar chart, frequency is expressed as the height of the bar; whereas in a histogram it is expressed as the area of the bar.
Unlike a bar chart, where the gaps between the bars stress the absence of a continuum on the x-axis, the gaps in a histogram have a different meaning. Because the x-axis is a continuum, a gap in the data indicates that there were no data values in this bin.
The shape of the histogram depends on the choice of x₀ and the bin-width, and making the wrong choice can led to flawed interpretations. Too many bins and you cannot see the structure of the data properly due to the presence of too much information; too few bins and you cannot see the structure at all. There are various methods for choosing the ideal bin-width, but none is definitive.
Also, Both are used differently.
The main differences are
A histogram is a very specific type of graph. A histogram is used in statistics to plot grouped data. It is in the form of a bar chart in which the bar widths represent the class intervals and the bar heights represent the frequency densities. As a result, the area of each bar is proportional to the frequency.
A histogram is a bar chart that only uses numbers.
A histogram when plotted as a bar diagram, shows the frequency or relative frequency of a set of data. An example of bar chart that is not a histograms would be a plot of the average salary of Americans from 1980 to year 2000. However, if the salaries were broken into groups, and a chart showed the number or percentage of Americans making less than $100,000 and those making more, this would be a histogram.

a histogram has intervals a bar graph does notAnswerA histogram has all the bars smooshed together while a bar graph has them apart. A bit more detail:A histogram looks sort of like mountains, valleys, and peaks. It goes up and down, depending on how the numbers change, with no break in between. A bar graph has columns which are straight up and down, with breaks (spaces) in between the columns.

A bar graph cannot have classes with different width. The height of a bar graph represents the frequency attributed to that class whereas in a histogram the area of a "bar" is proportional to the frequency, the height represents the frequency density.
They are almost same except directions, column chart are vertical type and bar chart are are horizontal.
You can only use the component bar chart when you have complete information. For instance, you must have totals and components to use the chart.
No. You can do that from a bar graph, a stem and leaf chart, a scatter plot, a cumulative frequency chart.
A histogram is a chart comprising bars but, unlike an ordinary bar chart, the widths (intervals) of the bars are different and their heights represent the frequency densities, not frequencies.
