以下是带符号的样条曲线图的示例。
我们已经在Highcharts Configuration Syntax一章中看到了用于绘制图表的配置 。 现在,我们将讨论带符号的样条图的示例。 我们还将了解所采取的其他配置/步骤。
配置 (Configurations)
使用marker.symbol属性将符号添加到一系列图表中。 它可以是预先配置的符号,如“square”,“diamond”或图像的url。 标记也可以添加到系列数据的任何位置。
系列 (series)
var series = [
{
name: 'Tokyo',
marker: {
symbol: 'square'
},
data: [7.0, 6.9, 9.5, 14.5, 18.2, 21.5, 25.2, {
y: 26.5,
marker: {
symbol: 'url(http://www.highcharts.com/demo/gfx/sun.png)'
}
}, 23.3, 18.3, 13.9, 9.6]
},
{
name: 'London',
marker: {
symbol: 'diamond'
},
data: [{
y: 3.9,
marker: {
symbol: 'url(http://www.highcharts.com/demo/gfx/snow.png)'
}
}, 4.2, 5.7, 8.5, 11.9, 15.2, 17.0, 16.6, 14.2, 10.3, 6.6, 4.8]
}
];
