数据被过滤chartJs时如何保持圆角?
我想出了这个 JSFiddle:
I came up with this JSFiddle : https://www.jsfiddle.net/gcb1dyou which has rounded chartJs bar corners.Problem is when legend clicked to filter data,corners disappear like below
当我点击橙色标签时,你可以看到黄色条上的圆形边框消失了.
When I clicked orange label as you can see rounded border disappeared on the yellow bar.
var lastVisible = 0;
for (var findLast = 0, findLastTo = this._chart.data.datasets.length; findLast < findLastTo; findLast++) {
if (!this._chart.getDatasetMeta(findLast).hidden) {
lastVisible = findLast;
if (this._chart.data.datasets[findLastTo - 1].data[this._index] == 0) {
lastVisible -= 1;
}
}
}在这里,我尝试添加另一个 if 以使 lastVisible findLast-1 当数据被隐藏(图例单击)并且先前的索引为空但不起作用时
} Here I tried to add another if to make lastVisible findLast-1 when data is hidden(legend clicked) and previous index is null but didn't work
else{
if(this._chart.data.datasets[findLastTo - 1].data[this._index] == 0){
lastVisible=findLastTo-2;
}
}
我该如何解决这个问题?期待看到你的答案.
How can I solve this?Expecting to see your answers.
推荐答案
我通过动态计算数据集的深度解决了这个问题.感谢回答
I fixed this problem by calculating the depth of dataset dynamically.Thanks for answers
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;
}
}
}
})
