Guys,

I have the following dataset:

LOAD * INLINE [

    Speler, Naam, Competitie, Leeftijd, Aantal goals, Salaris, Status, Ratio

    1, Piet, Premier League, 32, 100, 200000, Gehuurd, 93

    2,Sjaak, Primera Division, 32, 120, 200000, Gehuurd, 92

    3, Greet, Primera Division, 33, 140, 180000, Intern, 67

    4, Karel, Primera Divison, 23, 140, 220000, Intern, 72

];

These are my presentation settings:
