现行代码:

var canvas = document.getElementById('myChart');
var data = {
    labels: ["January"],
    datasets: [
        {
            label: "My First dataset",
            backgroundColor: "rgba(255,99,132,0.2)",
            borderColor: "rgba(255,99,132,1)",
            borderWidth: 2,
            hoverBackgroundColor: "rgba(255,99,132,0.4)",
            hoverBorderColor: "rgba(255,99,132,1)",
            data: [65, 59, 30, 81, 56, 55, 40],
        }
    ]
};
var option = {

};


var myBarChart = Chart.Bar(canvas,{
	data:data,
  options:option
});

<canvas id="myChart" width="400" height="500"></canvas>

一旦更新到最新版本的Chart.js(当前为v2.6.0),在条形图配置部分中,您可以设置一个maxBarThickness.这样做可以让您增加图表画布宽度,而无需担心条形变大.

您的options部分将如下所示:

var option = {
    scales: {
        xAxes: [{
            maxBarThickness: 100
        }]
    }
};

有关条形图配置选项的更多信息,请参阅以下文档:http:
//www.chartjs.org/docs/latest/charts/bar.html#configuration-options

根据您设置图表其余部分的方式,这些barPercentage和barThickness选项也可能适合您.

如果要将整个图表从画布边缘移开,可以使用布局填充选项:http://www.chartjs.org/docs/latest/configuration/layout.html

options: {
    layout: {
        padding: {
            left: 0,
            right: 50,
            top: 0,
            bottom: 0
        }
    }
}
