Highcharts 时间序列图表( 可缩放 )
下图是一个 Highcharts 时间序列图表
配置
图表
配置可缩放图表
配置属性 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
配置属性 plotOptions 设置图表区域
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
配置属性 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
}
}
}
