I have a code that has two problems:
(1) universalTransition doesn't work in the timeline context.
In each data property I have configured the groupId to work with its corresponding graph, but the transition does not occur in the context of timeline. Outside of timeline, the transition occurs normally.
(2) timeline: [{...}, {...}] doesn't seem to work (only the first object has an effect, as if there were an interference).
I set up the timeline with this format:
timeline: [
{...},
{...}
]
But this creates a problem, because the second timeline has no effect, even when you change the axisType, for example.

<div class="chart" style="width: 100%; height: 100vh"></div>I could solve this by using several instances, but I only want to keep one: chartUse.
EDIT
According to this answer, echarts only accepts a single timeline:
timeline: {...}
not:
timeline: [{...}, {...}]
So the question now lies in the universalTransition between charts that are not part of the timeline, i.e. gauge and pie charts (stuckSeries).The charts within the timeline use universalTransition normally, but how can it be applied to fixed charts as well, while maintaining the same instance (chartUse)?
1 Answer
Reset to default 0ECharts only supports one timeline object, not an array. Instead of:
timeline: [{...}, {...}]
Use:
timeline: {...}
For universalTransition to work with fixed charts (gauge ↔ pie), use setOption with replaceMerge: ["series"] to transition between different chart types while keeping the same instance (chartUse).
Modify your chartFrameSwitch1() function:
const option = {
series: series0
};
chartUse.setOption(option, { replaceMerge: ["series"] });
This ensures universalTransition applies to charts outside the timeline.
