I am using echarts to create a parallel chart. I am trying to create an emphasis on 2 elements at the same time but I feel like one of the element I am trying to create the emphasis on does not support it. Are there any workarounds where I would be able to highlight the categories when hovering a line in my sample code ?
Thanks
var dom = document.getElementById('chart-container');
var myChart = echarts.init(dom, null, {
renderer: 'canvas',
useDirtyRect: false
});
