参考一下ucharts的示例项目一个页面20多个图表，https://ext.dcloud.net.cn/plugin?id=271

把u-charts.js内的 getTouches 这个方法替换一下即可 function getTouches(touches, opts, e) { let x, y; if (touches.x) { if (opts.rotate) { y = opts.height - touches.x * opts.pix; x = touches.y * opts.pix; } else { x = touches.x * opts.pix; y = touches.y * opts.pix; } } else { if (opts.rotate) { y = opts.height - touches.clientX * opts.pix; x = (touches.pageY - e.currentTarget.offsetTop - (opts.height / opts.pix / 2) * (opts.pix - 1)) * opts.pix; } else { x = touches.clientX * opts.pix; y = (touches.pageY - e.currentTarget.offsetTop - (opts.height / opts.pix / 2) * (opts.pix - 1)) * opts.pix; } } return { x: x, y: y } }
