[GitHub] [incubator-echarts] LarsKoelpin opened a new issue #12221: Cannot
read property 'traverse' of undefined
LarsKoelpin opened a new issue #12221: Cannot read property 'traverse' of undefined
URL: https://github.com/apache/incubator-echarts/issues/12221
### Version
4.6.0
### Reproduction link
[https://jsfiddle.net/3zrLnvqp/](https://jsfiddle.net/3zrLnvqp/)
### Steps to reproduce
I attached a JS Fiddle.
When pressing "run" multiple times i get the error.
```javascript
echarts.min.js:22 Uncaught TypeError: Cannot read property 'traverse' of undefined
at e.incrementalRender (echarts.min.js:22)
at Hh.progress (echarts.min.js:22)
at tc (echarts.min.js:22)
at Hh.Zh.perform (echarts.min.js:22)
at echarts.min.js:22
at e.<anonymous> (echarts.min.js:22)
at Array.forEach (<anonymous>)
at E (echarts.min.js:22)
at eachSeries (echarts.min.js:22)
at Zd (echarts.min.js:22)
```
When it does not reproduce, increase the amount of data generated (name in example: INCREASE_ME_FOR_REPRODUCTION_CASE)
It may has to do with triggering a rerender too early, when the previous chart wasn't drawn completely
### What is expected?
The chart rerenders
### What is actually happening?
The error above occurs

That is a bug, happened when data count is larger than the [progressiveThreshold](https://echarts.apache.org/zh/option.html#series-scatter.progressiveThreshold), where progressive rendering is enabled.
To avoid this issue temporarily, we can simply set:
```js
series: [{
type: 'custom',
renderItem: renderItem,
progressive: 0, // Disable progressive
itemStyle: {
opacity: 0.8
},
data: data
}]
```

It seems that the issue does not depend on "setInverval". I also can reproduce the issue when drawing a custom chart with lots of data

The minimal `option` to reproduce this issue:
```js
option = {
yAxis: {
},
xAxis: {
},
series: [{
type: 'custom',
renderItem: function () {}, // the renderItem return nothing.
progressiveThreshold: 1, // Enable progressive when data item count > 1
data: [[123, 456], [654, 321]] // data item count is 2
}]
};
````
"`renderItem` is able to returns nothing" is a feature. It should be supported when progressive rendering enabled, rather than throw null pointer exception.
The bug need to be fixed.

Add some code in function of incrementalRender may fix this issue.
`
incrementalRender: function (params, customSeries, ecModel, api, payload) {
var data = customSeries.getData();
var renderItem = makeRenderItem(customSeries, data, ecModel, api);
function setIncrementalAndHoverLayer(el) {
if (!el.isGroup) {
el.incremental = true;
el.useHoverLayer = true;
}
}
for (var idx = params.start; idx < params.end; idx++) {
var el = createOrUpdate$1(null, idx, renderItem(idx, payload), customSeries, this.group, data);
**+ if (el)**
el.traverse(setIncrementalAndHoverLayer);
}
},`

The `progressive: 0` works like a charm but the charts are lagging so bad when the user is hovering a specific data point.
