Question

我获得了图表的一些数据，我需要它们的最大值。在我的成功中，我在$ scope.tempData中正确获得了这个值，但是如何在$ scope.options scaleStepWidth中使用它呢？

这是我的代码

    $scope.truc = [];
    $scope.tac = [];
    $scope.tic;
    $scope.tempData = 0;
    $scope.chargerStats = function () {

        var idProd = document.getElementById("idProduit").value;

        $http.post("{{path('pfcrm_phone_factory_graphe_nbventesproduitpartemps')}}", {id: idProd})
                .success(function (data, status, headers, config) {
                    $scope.data = data;
                    $scope.truc = $scope.data['datasets'];
                    $scope.tac = $scope.truc[0].data;

                    $scope.tempData = Math.max.apply(null, $scope.tac);

                })
                .error(function (data, status, headers, config) {

                    alert("Erreur pour l'affichage des graphiques");
                });

    };


    var steps = 3;
    // Chart.js Options
    $scope.options = {
        // Sets the chart to be responsive
        responsive: true,
        // Boolean - If we should show the scale at all
        showScale: true,
        // Boolean - If we want to override with a hard coded scale
        scaleOverride: true,
        // Number - The number of steps in a hard coded scale
        scaleSteps: steps,
        // Number - The value jump in the hard coded scale
        scaleStepWidth: 500,
        //Boolean - Whether the scale should start at zero, or an order of magnitude down from the lowest value
        scaleBeginAtZero: true,
        //Boolean - Whether grid lines are shown across the chart
        scaleShowGridLines: true,
        //String - Colour of the grid lines
        scaleGridLineColor: "rgba(0,0,0,.05)",
        //Number - Width of the grid lines
        scaleGridLineWidth: 1,
        //Boolean - If there is a stroke on each bar
        barShowStroke: true,
        //Number - Pixel width of the bar stroke
        barStrokeWidth: 2,
        //Number - Spacing between each of the X value sets
        barValueSpacing: 5,
        //Number - Spacing between data sets within X values
        barDatasetSpacing: 1
    };
});

非常感谢。

我通过将$ scope.option置于成功中解决了我的问题。非常感谢你的帮助。

如何使用＆＃34;数据＆＃34;从http.post角度请求出来的成功？
