Highcharts 调整曲线图的粗细、点大小、点形状

例子1：
粗细：lineWidth 默认值为2
 

plotOptions: {
    series: {
        marker: {
            radius: 3, //曲线点半径，默认是4
            symbol: ‘diamond’ //曲线点类型：”circle”, “square”, “diamond”, “triangle”,”triangle-down”，默认是”circle”
        }
    }
},

例子2：从官网例子上设置的

 

// Define a custom symbol path
Highcharts.SVGRenderer.prototype.symbols.cross = function (x, y, w, h) {
    return ['M', x, y, 'L', x + w, y + h, 'M', x + w, y, 'L', x, y + h, 'z'];
};
if (Highcharts.VMLRenderer) {
    Highcharts.VMLRenderer.prototype.symbols.cross = Highcharts.SVGRenderer.prototype.symbols.cross;
}


Highcharts.chart('container', {

    title: {
        text: 'Demo of predefined, image and custom marker symbols'
    },

    legend: {
        y: -40 // make room for subtitle
    },

    xAxis: {
        categories: ['Jan', 'Feb', 'Mar', 'Apr', 'May', 'Jun', 'Jul', 'Aug', 'Sep', 'Oct', 'Nov', 'Dec']
    },

    series: [{
        name: 'Predefined symbol',
        data: [29.9, 71.5, 106.4, 129.2, 144.0, 176.0, 135.6, 148.5, 316.4, 294.1, 195.6, 154.4],
        marker: {
            symbol: 'triangle'
        }
    }, {
        name: 'Image symbol',
        data: [216.4, 194.1, 95.6, 54.4, 29.9, 71.5, 106.4, 129.2, 144.0, 176.0, 135.6, 148.5],
        marker: {
            symbol: 'url(https://www.highcharts.com/samples/graphics/sun.png)'
        }
    }, {
        name: 'Custom symbol',
        data: [54.4, 29.9, 71.5, 106.4, 129.2, 144.0, 176.0, 135.6, 148.5, 216.4, 194.1, 95.6],
        marker: {
            symbol: 'cross',
            lineColor: null,
            lineWidth: 2
        }
    }],

    credits: {
        enabled: false
    },

    subtitle: {
        text: '*) Base64 not supported in IE6 and IE7',
        verticalAlign: 'bottom',
        align: 'right',
        y: null,
        style: {
            fontSize: '10px'
        }
    }
});
