Point Graph Series in Android
We have seen using a simple line graph and BarChart implementation in Android to represent data in the graphical format. Another graphical format for representing data is a point graph series. In this article, we will take a look at the implementation of the Point Graph Series in Android.
What we are going to build in this article?
We will be building a simple application in which we will be displaying sample data in a point graph view in Android. A sample video is given below to get an idea about what we are going to do in this article. Note that we are going to implement this project using the Java language.
Step by Step Implementation
Step 1: Create a New Project
To create a new project in Android Studio please refer to How to Create/Start a New Project in Android Studio. Note that select Java as the programming language.
Step 2: Add dependency to build.gradle(Module:app)
Navigate to the Gradle Scripts > build.gradle(Module:app) and add the below dependency in the dependencies section.
After adding the above dependency now sync your project and we will now move towards the implementation of our GraphView.
Step 3: Working with the activity_main.xml file
Navigate to the app > res > layout > activity_main.xml and add the below code to that file. Below is the code for the activity_main.xml file.
Step 4: Working with the MainActivity.java file
Go to the MainActivity.java file and refer to the following code. Below is the code for the MainActivity.java file. Comments are added inside the code to understand the code in more detail.
Now run your app and see the output of the app.
