$scope.generate = function() {
var ctx = element[0].getContext("2d");
ctx.canvas.width = $scope.references.self.width;
ctx.canvas.height = $scope.references.self.height;
$scope.instance = eval('new Chart(ctx).' +attr.isType+ '($scope.data,$scope.options)');
}

I'm getting errors inside Charts.js functions because of "data" var is undefined, this ocurred because inside the inicialization for the directive $watch'es you are not comparing if the old and new values are diferent, posible fix:

$scope.$watch('data', function (newValue, oldValue) {
if (newValue !== oldValue) $scope.generate();
}, true);

or at least create a 1.2 branch with new bower release.
