[GitHub] [echarts] krabouilleur opened a new issue, #18238: [Feature] the polyline icon effect doesn't follow multiple data of coords
krabouilleur opened a new issue, #18238:
URL: https://github.com/apache/echarts/issues/18238
### What problem does this feature solve?
Hi,
on serie type "line**S**" (not line but **lines**), where "polyline" is true,
- I've data array
- each element of the array represent a segment of the polyline
- I want to show an icon which "walks" on the line like this : https://echarts.apache.org/examples/en/editor.html?c=geo-svg-lines
but, this example is not my case because the generated line in this example was built is the same data object. data:
```
[
{
coords: [
[1, 2],
[3, 4]
[5, 6],
[7, 8]
]
}
]
```
In my case the line is generated by multiple segment of data (for many reasons)
```
[
{
coords: [
[1, 2],
[3, 4]
]
},
{
coords: [
[5, 6],
[7, 8]
]
}
]
```
Real example:
```
$.get(
ROOT_PATH + '/data/asset/geo/MacOdrum-LV5-floorplan-web.svg',
function (svg) {
echarts.registerMap('MacOdrum-LV5-floorplan-web', { svg: svg });
option = {
title: {
text: 'Visit Route',
left: 'center',
bottom: 10
},
tooltip: {},

]
}
]
}
]
};
myChart.setOption(option);
}
);
```
In this example:
- I can't use the "delay" on "effect" because the "icon" walks no at the same speed if a segment as a different length.
- multiple icons are showed
The feature I would want:
the effect should have a property to have a unique icon which walks on the line on each segment of data
### What does the proposed API look like?
**constantSpeedSegment**:
```
series: [
{
type: 'lines',
polyline: true,
effect: {
show: true,
symbol: '....',
constantSpeedSegment: 8,
},
data: [
{ coords: [ [ 0, 10], [10, 20] ] },
{ coords: [ [10, 20], [20, 30] ] },
]
}
]
```

I'm sorry to close this issue for it lacks the necessary title. Please provide **a _descriptive_ and as _concise_ as possible title to describe your problems or requests** and then the maintainers or I will reopen this issue.
Every good bug report or feature request starts with a title. Your issue title is a critical element as it's the first thing maintainers see.
A good issue title makes it easier for maintainers to understand what the issue is, easily locate it, and know what steps they'll need to take to fix it.
Moreover, it's better to include keywords, as this makes it easier to find the issue self and similar issues in searches.
