# Matplotlib Examples – A comprehensive guide to 40+ advanced visualization with code snippets

Matplotlib is a Python Programming library to create animated, static, and interactive visualizations. It offers various tools to create charts, simple graphs, and other visualizations. It can help us to analyze and present our given data.

With Matplotlib, we can create many plots. We can create scatter, lines, histograms, time series, bars, heat maps, etc. We can customize the appearance and style of our visualizations. We can use diverse options like line styles, font styles, color schemes, and marker types. It offers various features for adding legends, annotations, and other elements.

Let us now see more about the simple plots or charts. We can export it for reports, presentations, and web applications. It also supports various file formats making it easy to import our visualizations. We can see what we can create using Matplotlib with example outputs:

### 3D Scatter Plot:

A 3D Scatter plot can help display the relationship between three continuous variables. It is an extension of the traditional 2D scatter plot. It is useful when analyzing data that has more than two independent variables.

The other name for a box plot is a box-and-whisker plot. It helps display a set of continuous data allocations. It shows the quartiles, outliers, and median of the data. It offers a visual representation of the range and variability of the data.

We can learn how to create a box plot in Matplotlib in kandi.

### Violin Plot:

A violin plot can display the frequency distribution of a set of continuous data. It is like the boxplots. But, instead of showing the quartiles and outliers. It shows the kernel density estimation of the data.

Using kandi, we can learn how to create a violin plot in Matplotlib. ### Errorbar Plot:

An errorbar plot can display the uncertainty or variability of data. It shows the data’s standard deviation, mean, and confidence interval.

With kandi, we can learn how to create an errorbar plot using Matplotlib. ### Grid Plot:

Grid plots can be useful for comparing many datasets. It can help in exploring various visualizations or displaying various detail levels. In Matplotlib, a grid plot is a collection of different plots arranged in a grid pattern. Each plot will show a different subset of the data or a different analysis aspect.

Using kandi, we can learn how to create a grid plot using Matplotlib. ### Stream Plot:

A stream plot can help visualize the movement or flow of a fluid or a vector field. It is often used in engineering, geology, or physics to represent the behavior of air or fluid masses. It can also represent the movement of objects in a two-dimensional space.

A joy plot is also known as a ridgeline plot. We can stack density plots. It displays the distribution of continuous variables across various categories or groups. It is like a traditional density plot. But instead of overlaying the distribution on top of each other. It will arrange them with common axis coordinates, creating a mountain-like shape.

Let us see how to create a joy plot using Matplotlib. ### Kernel Density Estimate Plot:

A kernel density estimate plot can display a continuous variable’s probability density function. It is like a histogram, but it uses discrete bins. It will estimate the density of the data using a smooth curve called the kernel. It is useful for exploring the shape, variability of distribution, and central tendency. It will also help identify clusters or modes. ### Swarm Plot:

A swarm plot is also known as a beeswarm plot. It can display the distribution of a categorical variable on a continuous variable. It is like a scatter plot instead of placing the points. It will arrange them in a non-overlapping swarm along the axis labels. It can help show the individual observations, relative density, and potential outliers.

Let us learn how to create a swarm plot using Matplotlib. ### Calendar Heatmap:

Calendar Heatmap displays data over a conventional calendar year. We can share the days, weeks, and years on a light-to-gradient basis. It depends on the numeric value offered to the visualization. We can use it in different forms of analytics. But we can use it to show user behavior on a specific webpage template.

Let us learn about creating a Calendar heatmap using Matplotlib. ### Area Chart:

An area plot is a chart type that is like a line chart. But with the area under the line filled with color to represent the plotting of values. It can show how different datasets contribute to a complete or show changes in data over time.
