How to clear a chart from a canvas so that hover events cannot be triggered?

Question

I\'m using Chartjs to display a Line Chart and this works fine:

// get line chart canvas
var targetCanvas = document.getElementById(\'chartCanvas\').getConte         


        

Answer 1

First put chart in some variable then history it next time before init

#Check if myChart object exist then distort it

    if($scope.myChart) {
      $scope.myChart.destroy();
    }

    $scope.myChart  = new Chart(targetCanvas
