Introducing four types of plotting functions and relevant tricks for exploratory data analysis based on SeabornIntroductionViz 1: Double-axis Time Series Plot with Auxiliary Line/BandViz 2: Scatter Plot with Fitted TrendlineViz 3: Distribution Plot with KDE Line (Kernel Density Estimation)Viz 4: Categorical Bar Plot SeriesSummaryInitiatives“Matplotlib and seaborn are ugly, I only use ggplot2 in R”; “The seaborn API is a pain and very rigid to work with”; “The default plots for seaborn and matplotlib are so poor and I have…

Kind of the same, but also differentSeaborn is based on Matplotlib, and Pandas visualizations are Matplotlib objects, but even though they’re using the same backend, the way we plot our charts with each can be quite unique.Grouped bar charts — Image by the authorThis article will explore different bar charts to compare the usability, advantages, and disadvantages of Matplotlib, Pandas, and Seaborn for data visualization.We’ll start by defining some dummy data and importing the needed libraries.import pandas as pdimport…

Photo by Alexander Sinn on UnsplashThere is an excellent quote by Patrick Winston that says:Your success in life will be determined largely by your ability to speak, your ability to write, and the quality of your ideas, in that order”While he didn’t specifically say data visualization, I humbly believe he would agree that our ability to plot data falls within the writing category. And, as in writing, there are many pitfalls out there that we all can easily trip into unless we are well aware of them beforehand.In this…

This illustration is inspired by the Paleolithic rock painting in the Lascaux cave, signifying the acronym of our method, ROCK. Figuratively, the patterns of the rock art in the background (brown) are the 2D projections of the engineered dimeric construct of the Tetrahymena group I intron, while the main object in the front (blue) is the reconstructed 3D cryo-EM map of the dimer, with one monomer in focus and refined to the high resolution that allowed the collaborators to build an atomic model of the RNA.
