Plotting scatter plots
This recipe demonstrates how to use GRAL to draw scatter plots for 100,000 random data points. Scatter plots use both the x and y axes to plot data points and are a good means to demonstrate the correlation between variables.
- To use GRAL for plotting 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.zipfile from the download location into your local disk. Extract the files.
- Once you've downloaded the ZIP files and extracted them, you will see a directory structure as shown in the Getting ready section of the Plotting a 2D sine graph recipe. ...
