Jan 9, 2024 · In this article, we are going to see how to plot a histogram with various variables in Matplotlib using Python. A histogram is a visual representation of data presented in the form of groupings. It is a precise approach for displaying numerical data distribution graphically.

In Matplotlib, we use the hist() function to create histograms. The hist() function will use an array of numbers to create a histogram, the array is sent into the function as an argument. For simplicity we use NumPy to randomly generate an array with 250 values, where the values will concentrate around 170, and the standard deviation is 10.
Compute and plot a histogram. This method uses numpy.histogram to bin the data in x and count the number of values in each bin, then draws the distribution either as a BarContainer or Polygon. The bins, range, density, and weights parameters are forwarded to numpy.histogram.

Matplotlibis one of the most widely used data visualization libraries in Python. From simple to complex visualizations, it's the go-to library for most. In this tutorial, we'll take a look at how to plot a histogram plot in Matplotlib. Histogram plots are a great way to visualize distributions of data - In a histogram, each bar groups numbers into ...
We'll be using the Netflix Showsdataset and visualizing the distributions from there. Let's import Pandas and load in the dataset:
Now, with the dataset loaded in, let's import Matplotlib's PyPlot module and visualize the distribution of release_years of the shows that are live on Netflix: Here, we've got a minimum-setup scenario. We load the data into a DataFrame (df), then, we use the PyPlot instance and call the hist() function to plot a histogram for the release_yearfeatur...
Say, let's visualize a histogram (distribution) plot in batches of 1 year, since this is a much more realistic time-frame for movie and show releases. We'll import numpy, as it'll help us calculate the size of the bins: This time around, we've extracted the DataFrame column into a datavariable, just to make it a bit easier to work with. We've passe...
Sometimes, instead of the count of the features, we'd want to check what the density of each bar/bin is. That is, how common it is to see a range within a given dataset. Since we're working with 1-year intervals, this'll result in the probability that a movie/show was released in that year. To do this, we can simply set the density argument to True...
Other than these settings, there's a plethora of various arguments you can set to customize and change the way your plot looks like. Let's change a few of the common options people like to fiddle around with to change plots to their tastes: Here, we've set various arguments: 1. bins- Number of bins in the plot 2. density- Whether PyPlot uses count ...
In this tutorial, we've gone over several ways to plot a histogram using Matplotlib and Python. If you're interested in Data Visualization and don't know where to start, make sure to check out our bundle of books on Data Visualization in Python: Data Visualization in Python with Matplotlib and Pandasis a book designed to take absolute beginners to ...
Matplotlib histogram is used to visualize the frequency distribution of numeric array. In this article, we explore practical techniques like histogram facets, density plots, plotting multiple histograms in same plot.
