英文:
Thingsboard draw line on map not a polygon
问题
我想知道如何在Thingsboard中使用自定义小部件绘制地图上的线条。是否有人尝试过在其中使用JavaScript进行修改？
在这里要怎么做：
self.onInit = function() {
self.ctx.map = new TbMapWidgetV2('openstreet-map', false, self.ctx);
}
self.onDataUpdated = function() {
self.ctx.map.update();
}
self.onResize = function() {
self.ctx.map.resize();
}
self.actionSources = function() {
return TbMapWidgetV2.actionSources();
}
self.onDestroy = function() {
self.ctx.map.destroy();
}
self.typeParameters = function() {
return {
hasDataPageLink: true
};
}
这段代码应该放在哪里？
//这段代码应该放在哪里？
var lineCoordinates = [
{ lat: 37.774929, lng: -122.419418 }, // 起始点
{ lat: 37.804996, lng: -122.407547 } // 终点
];

I want to know how to draw lines on the map using custom widget in Thingsboard. Is there anyone who tried to modified inside using javascript?
how to do it here
self.onInit = function() {
self.ctx.map = new TbMapWidgetV2('openstreet-map', false, self.ctx);
}
self.onDataUpdated = function() {
self.ctx.map.update();
}
self.onResize = function() {
self.ctx.map.resize();
}
self.actionSources = function() {
return TbMapWidgetV2.actionSources();
}
self.onDestroy = function() {
self.ctx.map.destroy();
}
self.typeParameters = function() {
return {
hasDataPageLink: true
};
}
Where should I put this?
//where should i put this?
var lineCoordinates = [
{ lat: 37.774929, lng: -122.419418 }, // Start point
{ lat: 37.804996, lng: -122.407547 } // End point
];

很抱歉，使用默认的地图小部件作为自定义小部件的基础是不可能的。您必须从头开始完全创建自定义小部件。
但是，绘制线条也是可能的，而无需开发自己的小部件。这可以使用默认地图小部件直接实现：

Unfortunately, this is not possible with the default map widgets as the basis for a custom widget. You have to create the custom widget completely from scratch.
But drawing of lines is also possible without having to develop your own widget. This works out-of-the-box with default map widgets:
Widget Configuration:
Attribute:
[
