A Complete Guide to Plotting Categorical Variables with Seaborn

The Data

In this post we will use one of Seaborn’s conveniently available datasets about the Titanic, which I’m sure many readers have seen before. Seaborn has quite a few datasets ready to be loaded into Python to practice with; they are great for practicing data processing, exploration, and basic machine learning techniques.

titanic = sns.load_dataset('titanic')

titanic.head()

titanic.head()

titanic.info()

titanic['species'].unique()

titanic.info()

This data set is great because it has a decent number of entries — almost 900 — while also having an interesting story to dig into. There are lots of questions to ask and relationships between variables to explore making it a great example data set. Most critical for this article is that there is also a good mix of numerical and categorical variables to explore.

How to Make ECDF plot with Seaborn in Python?

ECDF plot, aka, Empirical Cumulative Density Function plot is one of the ways to visualize one or more distributions.

In this post, we will learn how to make ECDF plot using Seaborn in Python. Till recently, there was no out of the box function to make ECDF plot easily in Seaborn. With the Seaborn version 0.11.0 that became available we have function ecdfplot to make ECDF plot.

The ECDF plot has two key advantages. Unlike the histogram or KDE, it directly represents each datapoint. That means there is no bin size or smoothing parameter to consider. Additionally, because the curve is monotonically increasing, it is well-suited for comparing multiple distributions:

With the new Seaborn version we have two functions available to make ECDF plot. We will first use ecdfplot() function in Seaborn to ECDF plot and then also use Seaborn’s displot() function to ECDF plot. Let us load the libraries needed for making ECDF plot.

#ecdf plot #python #seaborn displot() #seaborn ecdfplot() #seaborn

Reference Variable in Java

Before We Started with the Reference variable we should know about the following facts.

**1. **When we create an object(instance) of class then space is reserved in heap memory. Let’s understand with the help of an example.

Demo D1 = new Demo();

Now, The space in the heap Memory is created but the question is how to access that space?.

Then, We create a Pointing element or simply called Reference variable which simply points out the Object(the created space in a Heap Memory).

**Understanding Reference variable **

1. Reference variable is used to point object/values.

**2. **Classes, interfaces, arrays, enumerations, and, annotations are reference types in Java. Reference variables hold the objects/values of reference types in Java.

3. Reference variable can also store null value. By default, if no object is passed to a reference variable then it will store a null value.

**4. **You can access object members using a reference variable using **dot **syntax.

Scope of a Variable In Java [With Coding Example]

Introduction

Programmers define the scope of a Variable in Java that tells the compiler about the region from where a variable is accessible or visible. The scope of a variable in Java is static by nature. It means we have to declare it at compile time only. In this article, you will learn about the scope of a Java variable along with its types
