WebbThe main difference is that bar charts are used for discrete (and non-numerical) data whilst histograms are used with continuous data, usually grouped in unequal class intervals. In a bar chart, the height (or length) determines the frequency. In a histogram, it is the area of a bar that determines the frequency. Webb13 juli 2024 · Almost always, equal interval choropleth maps result in an unequal count of countries per class. For example, class 1 has 113 countries out of 176 countries with four, five, six, and seven letters. However, only 2 countries have more than 20 letters.
