There are no gaps between bins on a histogram. That’s also why the width of the columns doesn’t represent anything in bar charts. That’s why if your variables are not numerical, a bar chart is a better fit to visualize your data. Histograms can only use numeric data as variables while bar charts can display categorical data on the x-axis. As we described above, a histogram presents the frequency distribution of data, while a bar chart compares categorical data within columns that are proportional to their values. However, there are concrete differences between a histogram and a bar chart. Histograms appear like bar charts, because they both use segmented columns, so they easily confuse each other. What is the difference between a histogram chart and a bar chart? Histogram charts group the data value bins along the x-axis of the chart, while it displays the distribution frequency along the y-axis (the amount or the percentage of the variable amongst others). It visualizes the frequency distribution by arranging the data values into bins and then presenting them as separate columns.
