Below I will share with you an example of using vue combined with Echarts to achieve click highlighting effect. It has a good reference value and I hope it will be helpful to everyone.
This article mainly introduces how to use Echarts in vue to achieve click highlighting effect.
1. First, take a look at the introduction on the official website:
http://echarts.baidu.com/api.html#action .graph.focusNodeAdjacency
2. Bind these two events during initialization. The events that need to be bound are mouse click events and right-click events.
mounted: function () { let that = this; let myChart = this.$echarts.init(document.getElementById('myChart')); myChart.on('click', function (params) { console.log(params); //点击高亮 that.myChart.dispatchAction({ type: 'focusNodeAdjacency', // 使用 dataIndex 来定位节点。 dataIndex: params.dataIndex }); if (params.dataType == 'edge') { that.handleClick(params); } else if (params.dataType == 'node') { if (that.firstNode == '') { that.firstNode = params.name; } else { that.secondNode = params.name; } } }); //取消右键的弹出菜单 document.oncontextmenu = function () { return false; }; //右键取消高亮 myChart.on('contextmenu', function (params) { console.log(params); that.myChart.dispatchAction({ type: 'unfocusNodeAdjacency', // 使用 seriesId 或 seriesIndex 或 seriesName 来定位 series. seriesIndex: params.seriesIndex, }) }); that.myChart = myChart; that.drawLine(); },
The running effect is as follows:
The above is what I compiled for everyone. I hope it will be helpful to everyone in the future.
