-When looking at the constructor, it is visible that the <code>DataSet</code> needs an <code>ArrayList</code> of type <code>Entry</code> and an integer value for the type. The type integer value can be chosen freely and can be used to identify the <code>DataSet</code> amongst other <code>DataSet</code> objects in the <code>ChartData</code> object. A possible type in this scenario could be a integer constant COMPANY_1. As an additional option, a label `String` can be specified for the `DataSet` which will be used in a `Legend`.
+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 `String` used to describe the `DataSet` and as a label for the `Legend`. Furthermore this label can be used to find the `DataSet` amongst other `DataSet` objects in the `Chartdata` object.
 
 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):
