                }
            ]
        }
        var ctxLineChart = $("#forecastLineChart").get(0).getContext("2d");
        var forecastImpactLineChart = new    Chart(ctxLineChart).Line(lineChartData);

Answer 1

定义图表的语法在版本2中发生了一些变化。小提琴。

var forecastImpactLineChart = Chart.Line(ctxLineChart, {
    data: lineChartData
});

或

var forecastImpactLineChart = new Chart(ctx, {
    type: 'line',
    data: lineChartData,
    options: options
});

Answer 2

代码中的打字错误(new中缺少"w"):

 var forecastImpactLineChart = new Chart(ctxLineChart).Line(lineChartData);
