I was trying to get some data from a server using Angular Factory and use it in Directive to draw some chart and the code looks like:

ChartApp.directive('hcPie', function (getGlucoseProfileReport) { 
    function link (scope, element, attrs) {
            getGlucoseProfileReport.getGlucoseProfileReport().success(function(response) {
                scope.glucoseProfile = response.jData;  
                console.log(scope.glucoseProfile);
            });            
            console.log(scope.glucoseProfile);

The first console displays the data as needed but the second one logs out undefined. So I am unable to use the data at a global scale. I would really appreciate your help or incite

You seem to be having an issue with the asynchronous nature of the service. To make sure you execute your code when you have retrieved the info, try wrapping the behavior in a $watch

scope.$watch("glucoseProfile", function(n, o){ If (n != o){ console.log(n); } });

  • Thanks Stewie and ruedamanuel, what you pointed out is right and now i am doing what i have to do with the data inside the success function for the time being and hope it works. – userJu Feb 16 '14 at 11:39
