Parallel plot, axes doesn't change if the data and dimensions are modified

### Version
4.9.0

### Reproduction link
[https://jsfiddle.net/ramgorur/cfor274e/latest](https://jsfiddle.net/ramgorur/cfor274e/latest)

### Steps to reproduce
Just follow the [`JSFiddle link`](https://jsfiddle.net/ramgorur/cfor274e/latest) and run the code. No setup necessary.

### What is expected?
If the `parallelAxis` and `series` are modified in `option` on the fly, the axes and the data should change accordingly.

### What is actually happening?
Let's say I have a parallel plot of 4-dimensional data. The `option` is like this:
```javascript
var option = { parallelAxis: null, series: null };

var myChart = echarts.init(document.getElementById("plot"));

option.parallelAxis = [
{ dim: 0, name: "f1" },
{ dim: 1, name: "f2" },
{ dim: 2, name: "f3" },
{ dim: 3, name: "f4" }
];
option.series = [{
data: data_4d,
lineStyle: { color: "red" },
name: "data_4d",
type: "parallel"
}];

myChart.setOption(option);
```

Now, if I change the option with different data and axes, like this:
```javascript
var opt = myChart.getOption();
opt.parallelAxes = [
{ dim: 0, name: "f1" },
{ dim: 1, name: "f2"},
{ dim: 2, name: "f3"}
];
opt.series = [{
data: data_3d,
lineStyle: { color: "red" },
name: "data_3d",
type: "parallel"
}];
myChart.setOption(opt);
```
The last axis still stays in the plot.

**Please note:** In the case of parallel and scatter plots, there are many options that can't be modified on the fly.

Not sure if this is a bug or I'm not doing it in a correct way
