Angular Highcharts：带时间序列可缩放的图表（Time Series, Zoomable Chart）
带时间序列可缩放的图表
现在让我们通过下面的例子来进一步理解带时间序列可缩放的图表。
配置
现在让我们讨论采取的其他配置/步骤。
chart
配置图表使其可缩放。chart.zoomType决定用户通过拖动鼠标缩放的尺寸。接受的值是x、y或xy。
var chart = {
zoomType: 'x'
};plotOptions
使用plotOptions配置图表区域。
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
}
};例子
