Hello,

I try to test map performance for one of our customers, unfortunately, i don’t succeed to make vector circle working well.

I try with these properties 🙂  
circle=  
[  
{  
“circles”: [  
{  
“lat”: 44.858856,  
“lng”: -0.5902  
}  
],  
“radius”: 50,  
“stroke”: {  
“enabled”: true,  
“color”: “#FF0322”,  
“weight”: 1,  
“opacity”: 1,  
“dashArray”: “”,  
“dashOffset”: “”,  
“lineCap”: “round”,  
“lineJoin”: “round”  
},  
“fill”: {  
“enabled”: true,  
“color”: “”,  
“opacity”: 1,  
“rule”: “nonzero”  
}  
}  
]

the only way to make the circle bigger and increase the weight value of the stroke.

Have you got any idea?

Best Regard

This is a very old conversation but it’s the only one on the subject and I just ran into the same problem. However, I think I have the answer: the radius seems to be specified in meters, not pixels.

This behavior makes a lot of sense because it means the circle scales sensiblywith zoom level. I think the the only problem is that the tooltip is wrong.
