Compare Bar Graphs and Histograms

Histograms are used to show distributions of variables whereas bar charts are used to compare variables. Histograms plot quantitative data with ranges of the data grouped into intervals while bar charts plot categorical data.

Note that there are no spaces between the bars of a histogram since there are no gaps between the intervals. On the other hand, there are spaces between the variables of a bar chart.
