-So, what is a <code>DataSet</code> and why do you need it? That is actually pretty simple. One <code>DataSet</code> objects represents a group or type of entries (values) inside the chart that belong together. It is designed to logically separate different groups of values in the chart. As an example, you might want to display the quarterly revenue of two different companies over one year. In that case, it would be recommended to create two different <code>DataSet</code> objects, each containing four values (one for each quarter). As an <code>ArrayList<String></code> to describe the legend on the x-axis, you would simply provide the four Strings "1.Q", "2.Q", "3.Q", "4.Q".

 Of course, it is also possible to provide just one <code>DataSet</code> object containing all 8 values for the two companys.

-When looking at the constructor, it is visible that the <code>DataSet</code> needs an <code>ArrayList</code> of type <code>Entry</code> and a type int. The type integer value can be chosen freely and can be used to identify the <code>DataSet</code>. A possible type in this scenario could be a constant COMPANY_1.

 The <code>ArrayList</code> of type <code>Entry</code> encapsulates all values of the chart. A <code>Entry</code> object is an additional wrapper around a value and holds the value itself, and it's position on the x-axis (the index inside the <code>ArrayList</code> of <code>String</code> of the <code>CharData</code> object the value is mapped to):
