在自定义标签下使用了这一代码，但是柱形图上一直无显示总和，是怎么回事？ function() {var point = this;var series = this.series;var points = this.points;/*获取当前分类下所有点*/var validPoints = points.filter(function(p) {return p.series.visible && p.visible && !p.isNull;/*获取当前分类下的有效点*/});var len = points.length;var vlen = validPoints.length;if (point == validPoints[vlen - 1]) {var value = 0;for (var i = -1; ++i < len;) {if (points[i].series.visible) {value += points[i].getTargetValue();/*获取点的值*/}}return value;/*返回相加后的值*/} else {return "";/*返回各个系列的值*/}} |
