效果图
文字省略
提示
如果是在x轴上的，就在x轴上添加triggerEvent: true,如果是y轴就在y轴添加，我是在y轴上添加的
并且自定义的方法（我取名为extension）
// echarts 横向省略文字 鼠标移入显示内容
export const extension = chart => {
// 注意这里，是以y轴显示内容过长为例，如果是x轴的话，需要把params.componentType == 'yAxis'改为xAxis
// 判断是否创建过div框,如果创建过就不再创建了
// 该div用来盛放文本显示内容的，方便对其悬浮位置进行处理
let elementDiv = document.getElementById("extension");
if (!elementDiv) {
let div = document.createElement("div");
div.setAttribute("id", "extension");
div.style.display = "block";
document.querySelector("html").appendChild(div);
}
chart.on("mouseover", function (params) {
console.log(params, "鼠标移入");
if (params.componentType == "yAxis") {
let elementDiv = document.querySelector("#extension");
//设置悬浮文本的位置以及样式
let elementStyle =
"position: absolute;z-index: 99999;color: #fff;font-size: 12px;padding: 5px;display: inline;border-radius: 4px;background-color: #303133;box-shadow: rgba(0, 0, 0, 0.3) 2px 2px 8px";
elementDiv.style.cssText = elementStyle;
elementDiv.innerHTML = params.value;
document.querySelector("html").onmousemove = function (event) {
let elementDiv = document.querySelector("#extension");
let xx = event.pageX - 10;
let yy = event.pageY + 15;
console.log("22", xx);
elementDiv.style.top = yy + "px";
elementDiv.style.left = xx + "px";
};
}
});
chart.on("mouseout", function (params) {
//注意这里，我是以y轴显示内容过长为例，如果是x轴的话，需要改为xAxis
if (params.componentType == "yAxis") {
let elementDiv = document.querySelector("#extension");
elementDiv.style.cssText = "display:none";
}
});
};
然后我放在末尾引入的
