URL: https://github.com/apache/echarts/issues/18167
### Version
5.4.0
### Link to Minimal Reproduction
_No response_
### Steps to Reproduce
Hello!
I have multiple charts with either one or two series each, all of which are
grouped together.
The options are based on the content of the plot, however, they are all:
```
xAxis: {
type: 'time',
},
series: [
{
type: 'line',
animationDuration: 500,
data: this.data[0].map((x) => [x.datetime, x.value.toFixed(2)]),
connectNulls: true,
symbol: 'none',
showAllSymbol: true,
markLine: {
silent: true,
animation: false,
lineStyle: {
color: '#333',
},
label: {
show: false,
},
symbol: 'none',
data: this.markLine[this.sensor.feature] ?? null,
},
},
]
```
### Current Behavior
I am currently transitioning from a different charting library and have
noticed an issue:
Sometimes, not all of the charts have data for the specified time range. In
the old library, it was obvious that data was missing because the x axis (time)
was the same for all charts, so there would be gaps. In echarts, however, the x
axis seems to adapt to the available data rather than the selected time range.
This means that if you don't pay attention, you don't realize that data is
missing.

### Expected Behavior
What I would like to see is that data stopped coming in, i.e. use the entire
x axis and see a blank space where data is missing.

### Environment
```markdown
- OS: Windows 10
- Browser: Chrome 108.0.5359.126 (Official Build) (64-bit)
- Framework: Vue
```
### Any additional comments?
I found some posts on SO suggesting to add null entries for missing
timestamps, however, that seems highly inefficient and I was hoping that there
was another way of solving this issue.
Thanks for your help!
