我自己解决了，在条件显示里设置就可以了，像我这个系列有四个，就拆成了两个两个算。具体如下：

代码分别为：

function sumLabel(){

  const point = this;

  const points = point.points;

  const validPoints = points.filter( (point) => point.isVisible() );

  if(point == validPoints[(validPoints.length/2)-1]){

    let value = 0;

    for(let i = 0; i < validPoints.length/2; i++){

      value += validPoints[i].value;

    }

          return value; 

  } else {

    return "";

  }

}

function sumLabel(){

  const point = this;

  const points = point.points;

  const validPoints = points.filter( (point) => point.isVisible() );

  if(point == validPoints[validPoints.length-1]){

    let value = 0;

    for(let i = (validPoints.length/2); i < validPoints.length; i++){

      value += validPoints[i].value;

    }

          return value; 

  } else {

    return "";

  }

}

不是有解释吗，直接后面 return value
