当数据为0时，如何使chartJs堆积条始终四舍五入？

问题描述

我想到了这个小提琴：

您可以在此处看到黄色的未舍入的单位。如何解决这个问题

解决方案

感谢大家的回答。我在下面尝试了一下，并完美地处理了任意数量的数据集。

  var lastVisible; 
 var datasLength = this._chart.data.datasets.length; 
 this._chart.data.datasets.map（（e，index）=> {
 lastVisible = datasetsLength-1; 
 //查找数据集的深度并获取非零值值
 for（var i = lastVisible; i> 0; i-）{
 if（！this._chart.getDatasetMeta（i）.hidden）{
 if（this._chart。 data.datasets [i] .data [this._index]！= 0）{
 lastVisible = i; 
中断； 
} 
} 
} 
}）
  

I came up with this Fiddle : https://jsfiddle.net/2s09hqLu/ which has stacked rounded chart as I wanted.But problem is when a value is 0 in data array.It doesnt make it rounded.I always want it to be rounded how can I do that?

data: [20, 5, 0, 15, 12, 13]

As you can see here on the yellow its flat not rounded.How can I solve this problem?

解决方案

Thanks everyone for answers.I tried below and worked perfectly for any amount of datasets.

var lastVisible;
  var datasetsLength = this._chart.data.datasets.length;
  this._chart.data.datasets.map((e,index)=>{
    lastVisible=datasetsLength-1;
    //to find the depth of datasets and get non-zero value
    for(var i=lastVisible;i>0;i--){
    if(!this._chart.getDatasetMeta(i).hidden){
      if(this._chart.data.datasets[i].data[this._index] != 0){
        lastVisible = i;
        break;
      }
    }
    } 
  })
