Steps to Reproduce

var chart1 = echarts.init(document.getElementById("chart1")); var option1 = { title: { text: "chart1" }, tooltip: { trigger: "axis" }, legend: { data: ["今天", "昨天", "上周"] }, xAxis: { data: ["8:00", "10:00", "12:00", "14:00", "16:00", "18:00", "20:00"] }, yAxis: {}, series: [ { name: "上周", type: "line", data: [10, 35, 20, 13, 16, 18, 41] } ] }; var chart2 = echarts.init(document.getElementById("chart2")); var option2 = { title: { text: "chart2" }, tooltip: { trigger: "axis" }, legend: { data: ["今天", "昨天", "上周"] }, xAxis: { data: ["8:00", "10:00", "12:00", "14:00", "16:00", "18:00", "20:00"] }, yAxis: [{}], series: [ { name: "上周", type: "line", data: [10, 35, 20, 13, 12, 18, 41] } ], dataZoom: [ { yAxisIndex: 0, filterMode: "none", startValue: 20, endValue: 30 } ] };

chart1.setOption(option1); chart2.setOption(option2); chart1.group = "group1"; chart2.group = "group1"; echarts.connect("group1");

产生这种现象的原因应该是axisTrigger中会判断该点是否在坐标系中

The reason for this phenomenon should be that axisTrigger will determine whether the point is in the coordinate system

I don't think it is a bug. It makes sense to me not to show the pointer if no point is shown at the position. When you put mouse at the zoomed chart, axispointer will be displayed correctly.

系统貌似只会根据seriesIndex=0去判断是否有无数据，如果chart中有两个series，series0数据超出坐标系，series1数据在坐标系中依然会不现实axisPointer, 比如下列情况 ，

两个chart联动时，如果x轴数据在坐标系中，保持x轴有效是不是更合理？
