问题描述

好的，我有以下代码:

    var element = document.getElementById(scope.changeid);

function getData(division,redraw) {
    var employeeData = [];
    if (!division) {
        $http.get(api.getUrl('competenceUserAverageByMyDivisions', null)).success(function (response) {
            processData(response,redraw);
        });
    }
    else {
        $http.get(api.getUrl('competenceUserAverageByDivision', division)).success(function (response) {
            processData(response,redraw);
        })
    }

}

function processData(data,redraw) {
    var y = [],
        x1 = [],
        x2 = [];

    data.forEach(function (item) {
        y.push(item.user.profile.firstname);
        x1.push(item.current_level);
        x2.push(item.expected);
    });

    var charData = [{
            x: x1,
            y: y,
            type: 'bar',
            orientation: 'h',

            name: 'Nuværende'
        }, {
            x: x2,
            y: y,
            type: 'bar',
            orientation: 'h',

            name: 'Forventet'
        }],
        layout = {
            barmode: 'stack',
            legend: {
                traceorder: 'reversed',
                orientation: 'h'

            }
        };

    if(!redraw){
        Plotly.plot(element, charData, layout);
    }
    else
    {
        Plotly.redraw(element,charData,layout);
    }
}

scope.$watch('divisionId', function (newValue, oldValue) {
    if (newValue) {
        getData(newValue.id,true);
    }
}, true);

getData(null,false);

创建以下图表:

现在你可以看到我添加了一个 watcher

Now as you can see ive added a watcher

            scope.$watch('divisionId', function (newValue, oldValue) {
            if (newValue) {
                getData(newValue.id,true);
            }
        }, true);

现在当我触发它时，它应该更新图表并调用 Plotly.redraw(element,charData,layout);

Now when i trigger this it should update the chart and call Plotly.redraw(element,charData,layout);

但是，当它这样做时，图表根本不会改变.控制台没有错误，所以我不太确定该怎么办?

However when it does this the chart does not change at all. There is no error in the console so i am not quite sure what to do?
