Bar plots are the most common graph types used by data scientists. It is simple to draw a bar chart using GRAL. In this recipe, we will be using GRAL to plot the following bar chart:
To use GRAL to plot bar charts, we need the example applications provided with the library in the form of Jar files. These example applications can be downloaded from http://trac.erichseifert.de/gral/wiki/Download. Download the
gral-examples-0.10.zip
file from the download location into your local disk. Extract the files.Once you download the ZIP files, and extract them, you will see a directory structure as shown in the Getting ready section of the Plotting a 2D sine graph recipe, where our folder of interest is the
lib
folder.Inside the
lib
folder, you will find three Jar files:gral-core-0.10
,gral-examples-0.10
, andVectorGraphics2D-0.9.1
. In this recipe, you will be using the first two of the aforementioned Jar files.Include these two JAR files in your project as external...
