使 angular-chartjs 响应 UI-Grid

Question

我正在使用 angular-chart.js (http://jtblin.github.io/angular-chart.js/) module and trying to make the chart data editable with UI-Grid module (http://ui-grid.info/docs/#/tutorial/201_editable)。我能够编辑数据，但不确定如何在编辑单元格时响应地更新图表。我正在与此抗争，因为 sometime.I 感谢对此的任何想法。

这是我目前得到的：

app.controller("myController", function ($scope) {

$scope.labels = ["January", "February", "March", "April", "May", "June", "July"];
$scope.series = ['Series A', 'Series B'];

$scope.gridOptions = {
    columnDefs: [
        { name: 'A', width: '50%', enableCellEdit: true },
        { name: 'B', width: '50%', enableCellEdit: true }
    ],
    data: [{
        "A": 65,
        "B": 28
    },
    {
        "A": 59,
        "B": 48
    },
    {
        "A": 80,
        "B": 40
    },
    {
        "A": 81,
        "B": 19
    },
    {
        "A": 56,
        "B": 86
    },
    {
        "A": 55,
        "B": 27
    },
    {
        "A": 40,
        "B": 90
    }
    ]
};

var seriesA = [];
for (var i = 0; i < $scope.gridOptions.data.length; i++) {
    seriesA.push($scope.gridOptions.data[i].A);
}

console.log(seriesA);

var seriesB = [];
for (var i = 0; i < $scope.gridOptions.data.length; i++) {
    seriesB.push($scope.gridOptions.data[i].B);
}

console.log(seriesB);

$scope.data = [
        seriesA,
        seriesB
];


$scope.onClick = function (points, evt) {
    console.log(points, evt);
};
});

这是 HTML 片段：

<div id="grid1" class="panel" ui-grid="gridOptions" ui-grid-edit ui-grid-row-edit ui-grid-cellNav class="grid"></div>
<canvas id="line" class="chart chart-line" data="data"
    labels="labels" legend="true" series="series"
    click="onClick"></canvas>

Answer 1

只需在 canvas 中指定 data="gridOptions.data" ，当数据发生变化时它会自动更新。

Answer 2

您只设置了一次 data。要使这个动态化，你需要做的就是将它指向一个从网格数据计算数据的范围方法，就像这样

脚本更改

定义一个函数来根据网格数据计算图表数据结构。使用它来初始化图形并在单元格编辑完成后更新图形

var getData = function () {
    var seriesA = [];
    for (var i = 0; i < $scope.gridOptions.data.length; i++) {
        seriesA.push($scope.gridOptions.data[i].A);
    }

    console.log(seriesA);

    var seriesB = [];
    for (var i = 0; i < $scope.gridOptions.data.length; i++) {
        seriesB.push($scope.gridOptions.data[i].B);
    }

    console.log(seriesB);

    return [
        seriesA,
        seriesB
    ];
}

$scope.data = getData();

$scope.gridOptions.onRegisterApi = function (gridApi) {
    $scope.gridApi = gridApi;
    gridApi.edit.on.afterCellEdit($scope, function () {
        $scope.data = getData();
    });
};

现在，编辑网格条目将自动更新图表。
