Tip! If you’re working in the Jupyter environment, be sure to include the %matplotlib inline Jupyter magic to display the histogram inline. This hist function takes a number of arguments, the key one being the bins argument, which specifies the number of equal-width bins in the range. Note that it does not make sense to rearrange the bars of a histogram. To create a histogram in Python using Matplotlib, you can use the hist() function. Histograms plot quantitative data with ranges of the data grouped into bins or intervals while bar charts plot categorical data.

If you want to be able to save and store your charts for future use and editing, you must first create a free account and login - prior to working on your charts. Creating a Histogram in Python with Matplotlib × You are not logged in and are editing as a guest. It might make sense to split the data in 5-year increments. A histogram is a chart that groups numeric data into bins, displaying the bins as segmented columns. We can see from the data above that the data goes up to 43. There are different types of distributions, such as normal distribution, skewed distribution, bimodal distribution, multimodal distribution, comb distribution, edge peak distribution, dog food distributions, heart cut distribution, and so on. We can then create histograms using Python on the age column, to visualize the distribution of that variable. The histogram can be classified into different types based on the frequency distribution of the data.
We’ll use the data from my eBook Introduction to Python for Data Science – specifically, the age column. Let’s begin by loading the required libraries and our dataset. The histogram can turn a frequency table of binned data into a helpful visualization: Loading our Dataset

If you want to learn how to create your own bins for data, you can check out my tutorial on binning data with Pandas. The shape of the histogram displays the spread of a continuous sample of data. The taller the bar, the more data falls into that range.
