Matplotlib is a powerful visualization package for Python. It is very customizable, thanks to this it is widly used in commercial and in academic use cases. In this article, I will show you 9 different ways how to set colors in Matplotlib plots. All parts of the plot can be customized with a new color. You can set colors for axes, labels, background, title. However, not every data scientist is a graphic designer that can compose nice looking colors in a single plot, so I can show you how to use predefined Matplotlib styles to get attractive plots.

There are also external libraries that have many extra colormaps, which can be viewed in the Third-party colormaps section of the Matplotlib documentation. Here we briefly discuss how to choose between the many options. For help on creating your own colormaps, see Creating Colormaps in Matplotlib. The idea behind choosing a good colormap is to find a good representation in 3D colorspace for your data set. The best colormap for any given data set depends on many things including:. Whether representing form or metric data [Ware]. Your knowledge of the data set e. For many applications, a perceptually uniform colormap is the best choice; i. Researchers have found that the human brain perceives changes in the lightness parameter as changes in the data much better than, for example, changes in hue. Therefore, colormaps which have monotonically increasing lightness through the colormap will be better interpreted by the viewer. Wonderful examples of perceptually uniform colormaps can be found in the Third-party colormaps section as well. Color can be represented in 3D space in various ways. An excellent starting resource for learning about human perception of colormaps is from [IBM].

The Color tutorials and examples demonstrate how to set colors and colormaps. You may want to read those instead. This module includes functions and classes for color specification conversions, and for mapping numbers to colors in a 1-D array of colors called a colormap. Mapping data onto colors using a colormap typically involves two steps: a data array is first mapped onto the range using a subclass of Normalize , then this number is mapped to a color using a subclass of Colormap. Two subclasses of Colormap provided here: LinearSegmentedColormap , which uses piecewise-linear interpolation to define colormaps, and ListedColormap , which makes a colormap from a list of colors.

Turn your dataframe into an interactive web app with one click! Data Visualization is a crucial skill in the toolkit of any data scientist. It helps to understand complex data, find patterns, and develop intuitions that guide Machine Learning algorithms. Among the popular data visualization libraries in Python, one stands out - Matplotlib. Its power and versatility enable you to create a wide array of static, animated, and interactive plots. In this tutorial, we'll dive deep into a critical aspect of data visualization - Colormaps in Matplotlib. PyGWalker opens in a new tab can simplify your Jupyter Notebook data analysis and data visualization workflow, by turning your pandas dataframe and polars dataframe into a Tableau-style User Interface for visual exploration. Colormaps are a vital part of Visual Data Analysis. They map data values to colors, helping our brains recognize patterns in the data. Matplotlib provides a variety of build-in colormaps, ranging from sequential colormaps, diverging colormaps, qualitative colormaps, to cyclic colormaps.
