配置
图表
配置可缩放图表。 chart.zoomType 指定了用户可以拖放的尺寸,用户可以通过拖动鼠标来放大,可能值是x,y或xy:
var chart = {
zoomType: \'x\'
};
plotOptions
使用 plotOptions 配置图表区域:
配置两个 Y 轴:
var plotOptions = {
area: {
fillColor: {
linearGradient: { x1: 0, y1: 0, x2: 0, y2: 1},
stops: [
[0, Highcharts.getOptions().colors[0]],
[1, Highcharts.Color(Highcharts.getOptions().colors[0]).setOpacity(0).get(\'rgba\')]
]
},
marker: {
radius: 2
},
lineWidth: 1,
states: {
hover: {
lineWidth: 1
}
},
threshold: null
}
};
plotOptions
plotOptions用于设置图表中的数据点相关属性。
var plotOptions = {
series: {
cursor: \'pointer\',
point: {
events: {
click: function (e) {
hs.htmlExpand(null, {
pageOrigin: {
x: e.pageX || e.clientX,
y: e.pageY || e.clientY
},
headingText: this.series.name,
maincontentText: Highcharts.dateFormat(\'%A, %b %e, %Y\', this.x)
+ \':<br/> \' + this.y + \' visits\',
width: 200
});
}
}
},
marker: {
lineWidth: 1
}
}
}
