Drawing a circle around a point in vue2-google-maps

Question

I am using Vue to build a site that takes in some data and displays a google map with markers and circles around the points with the markers.

So far I can create the map with markers perfectly fine, however I have no idea what the proper way to create a circle is with the Vue2-google-maps package, despite having combed through the Documentation for a long time.

Here is the code so far

    <GmapMap
      :center="center"
      :zoom="10"
      class="google-map">
        <GmapMarker
          :key="index"
          v-for="(pin, index) in markers"
          :position="pin.position"
          :icon="pin.icon"
          :clickable="true"
          :draggable="true"
          @click="center=pin.position">
        </GmapMarker>
        <GmapCircle
          :key="index"
          v-for="(pin, index) in markers"
          :center="pin.position"
          :radius="1000"
          :visible="true"
          :fillColor="red"
          :fillOpacity:="1.0">
        </GmapCircle>
    </GmapMap>

Note that markers is a list of markers that is created somewhere else in the code.

If you take out the tags, the code works perfectly fine placing all the markers. I just need to know what the proper tag/object set is for creating a circle.

You are on the right track, GmapCircle component in vue2-google-maps library is intended for creating circles on the map. There are might be several reasons why circles are not getting displayed:

center property value is invalid, the supported format is {lat: <lat>, lng: <lng>} or google.maps.LatLng value
maybe you could not spot them due to relatively small size (given the provided 2 kilometer diameter, they could be easily missed)?

Regarding fillColor and fillOpacity properties, they need to be passed via options property, e.g. :options="{fillColor:'red',fillOpacity:1.0}"

Anyway the following example demonstrates how to create circles on map via vue2-google-maps

<GmapMap :center="center" :zoom="zoom" ref="map">
  <GmapCircle
    v-for="(pin, index) in markers"
    :key="index"
    :center="pin.position"
    :radius="100000"
    :visible="true"
    :options="{fillColor:'red',fillOpacity:1.0}"
  ></GmapCircle>
</GmapMap>



export default {
  data() {
    return {
      zoom: 5,
      center: { lat: 59.339025, lng: 18.065818 },
      markers: [
        { Id: 1, name: "Oslo", position: { lat: 59.923043, lng: 10.752839 } },
        { Id: 2, name: "Stockholm", position: { lat: 59.339025, lng: 18.065818 } },
        { Id: 3,  name: "Copenhagen", position: { lat: 55.675507, lng: 12.574227 }},
        { Id: 4, name: "Berlin", position: { lat: 52.521248, lng: 13.399038 } },
        { Id: 5, name: "Paris", position: { lat: 48.856127, lng: 2.346525 } }
      ]
    };
  },
  methods: {}
};

Thank you! Worked like a charm! – wjmccann Jan 02 '19 at 20:54 — wjmccann, Jan 02 '19 at 20:54

in my case, i had error that saw:" GmapCircle not define component", so i have used this code:

<gmap-circle
                    v-for="(infoWindow, index) in arrayMarkers"
                     :key="'circle_'+index"
                     radius="100"
                    :center="infoWindow.position"
 
                />
