- 插入折线
// 插入折线 function appendLineToChart(name, data, zeroData) { var line = { name: name, type: 'line', xAxisIndex: 0, smooth: false, connectNulls: true, data: data, markLine: { lineStyle: { type: 'dashed' }, data: zeroData } } option.series.push(line); chart.setOption(option); }
- 清除折线
function removeLineFromChart(name) { var index = -1; for (var i = 0; i < option.series.length; i++) { if (option.series[i].name == name) { index = i; break; } } if (index > -1) { option.series.splice(index, 1); chart.setOption(option, true); // 设置option不合并(覆盖) } }
- 对于其中的交互和传值可以动态的去创建对象
