请帮助。您的代码有几个问题 首先，您的数据集应该有大量的标签，这样您就不能忽略空白位置而不填充它们。要解决此问题，您需要进行更改 $parsedAry['dataset'][$i]['data']=array；到$parsedAry['datasets'][$i]['data']=array0,0,0,0 这将在您的数据集中添加5个空白点 第二，你必须把数字放在正确的位置，你必须为你的最后一个循环添加一个计数器来识别正确的位置 最后，您的代码应该是这样的
虽然代码太多，但我认为问题在于数组_push$parsedAry['datasets'][$keySev]['data']，$v1['Count']；，您需要执行类似于$parsedAry['datasets'][$keySev]['data'][$weekSlot]=$v1['Count']的操作。使用array_push只是从0添加项目，从标签中可以看到[0]=>>4周。非常感谢。我尝试了很多东西。这很有效。非常感谢。
