用这个自定义js语句

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 = 0; i < validPoints.length; i++){

      value += validPoints[i].value;

    }

    return this.value+"  合计"+value;

  } else {

    return this.value;

  }

}
