@John8848 我也有同样的需求 |
|
正好我今天也有这个需求，基于echarts3.6.2整合其他牛人的代码之后的文件。 |

事隔半年才发过来！正用的时候没有回复？

今天我刚修改了一份3.6.2的，基于之前别的代码。
var defaultHtml = dataModel.formatTooltip(dataIndex, e, false, dataType);
`formatTooltip: function (dataIndex,e) {
//compute the anti-clockwise angle of mousePos-coordinate -- Y-line.
var getAngle = function(mx,my,px,py){
console.log(mx+","+my+","+px+","+py);
var x = Math.abs(px-mx);
var y = Math.abs(py-my);
var z = Math.sqrt(Math.pow(x,2)+Math.pow(y,2));
var cos = y/z;
var radina = Math.acos(cos);
var angle = Math.floor(180/(Math.PI/radina));
if(mx>px && my>py){
angle = 180-angle;
}
if(mx==px && my>py){
angle = 180;
}
if(mx>px && my==py){
angle = 90;
}
if(mx<px && my>py){
angle = 180+angle;
}
if(mx<px && my==py){
angle = 270;
}
if(mx<px && my<py){
angle = 360-angle;
}
//the Echarts radar turns anti-clockwise.
return 360-angle;
};
//get index by angle;
var getIndexToDisplay = function(num,angle){
var filterIndex =0;
for(var i=0; i<num; i++){
if(angle>(360/num*i-360/num/2) && angle<(360/num*i+360/num/2)){
filterIndex = i;
break;
}
}
return filterIndex;
};
var value = this.getRawValue(dataIndex);
var coordSys = this.coordinateSystem;
//get index by position of mouse.
var index = getIndexToDisplay(value.length,getAngle(e.offsetX,e.offsetY,coordSys.cx,coordSys.cy));
var indicatorAxes=coordSys.getIndicatorAxes();
var tipHtml=indicatorAxes[index].name;
var len=this.getData().count();
for(var i=0;i<len;i++){
tipHtml+='<br/>'+this.getData().getName(i)+' : '+this.getRawValue(i)[index]
}
return tipHtml;
//region code, display all data of this series.
/*return (this._data.getName(dataIndex) == '' ? this.name : this._data.getName(dataIndex)) + '<br/>'
+ zrUtil.map(indicatorAxes, function (axis, idx) {
return axis.name + ' : ' + value[idx];
}).join('<br />');*/
},`

@dantelife 用了你上面那个 发现雷达图周围一圈文字没有了 |
|
@mmmaomao21 不应该，好好看下你option。具体什么情况？贴图看看。 |
我想问下用NPM包的话怎么用回你的js |
我发现可以用了 请问一下用这个js包的话 可以拿到回调的params吗 而不是直接显示出来 |
