Thanks @helgasoft and @Yatekii for your fast feedback.
Currently, I order the keys dynamically according to dataset length as a
hotfix, which seems to be the easiest and most performant way (for larger
datasets). In my setup using Vue-ECharts (I have a streaming, multi-axis,
multi-plot chart with interactive zoom decimation/loading), this seems to work
quite good.
1. I do not see null filling as a satisfying hotfix, as it is adding
additional workload.
2. I do not see splitting the dataset into multiple pairs as a good solution
either, as I now have to compute the datasetIndex for more complex scenarios
(which I have):
```javascript
option = {
xAxis: { },
yAxis: { },
series: [
{
type: 'line',
encode: {
x: 'smallX',
y: 'smallY',
},
},
{
type: 'line',
encode: {
x: 'largeX',
y: 'largeY',
},
datasetIndex: 1 // Now we need to determine dataIndex, which is not
easier.
}
],
dataset: [
{
source: {
smallX: [10, 20, 30],
smallY: [3.141, 7, 5]
}
},
{
source: {
largeX: [9, 11, 13, 15, 17, 19, 21, 23, 25, 27, 29, 31],
largeY: [1, 2, 3, 4, 5, 7, 8, 9, 10, 12, 13, 14, 15]
}
}
],
};
```
In the end, even if the behaviour is documented, it is
* **Not intuitive** and therefore not to be anticipated by the user.
* It is **hard to detect in the first place** (e.g. two datasets with
similar, but not identical length). This is why I did not discover this issue
early on in more complex charts.
* On the surface, a fix might not be that hard to implement, as the correct
ordering **already is working with sorted named datasets** (?).
Best regards
