Chartjs-Vue-chartjs remove top rectangle (datasets label)

You litterly posted the answer yourself, the second object in the renderChart function is the options object so if you put it like this it will work:

{ responsive: true, maintainAspectRatio: true, legend: { display: false } }

Next time please dont post a screenshot of your code but include it as text in your post since it is a lot easyer to read and use for people
