Plotting a 2D sine graph

In this recipe, we will use a free Java graph library named GRAphing Library (GRAL) to plot a 2D sine graph. On many occasions, sine graphs can be particularly useful for data scientists since they are a trigonometric graph that can be used to model fluctuations in data (for example, using temperature data to create a model that predicts the times during the year that a location would be pleasant to visit).

Getting ready

To use GRAL in your project, you need to download the GRAL JAR file and include it in your project as an external Java library. To download the Jar file, go to http://trac.erichseifert.de/gral/wiki/Download and download GRAL JAR file version 0.10 from the legacy version section. The file that you are going to download is a zip file named gral-core-0.10.zip:

Once you download the file, extract the files and you will see the files and folders in the distributions. Among them, you will find a folder named lib, which is the folder of interest.
