Show value in label but remove out of chart (chartjs) - chart.js

Question

Hi guys quit knew in the JS world so I have a question,
Anoyone knows how I can get the variable ' Totaal_dataset' only in the label of the chart and not as a 3rd bar in the chart?
Below the code and the ability to play with it. It's a compound interest calculator.
