Pa_Lotus

Hi

in my case i have some graphic points and i'm looking for filtering points based on geometry

for example

assigning color to graphic points

if point is inside los angeles then green color

else red color

no idea how to validate point geometry with area

Any suggestions?

Thanks

Hi,

Depends on how you are loading the points, you can check point within polygon using the following method;

Polygon | API Reference | ArcGIS API for JavaScript 3.27 

let boolean = PolygonFeature.contains(PointFeature); //This returns a boolean that will let you know if the point lies within a polygon.

you can use this to set attributes to the point feature and then use Unique Value Renderer, or you can run a loop to check condition and then change the color of the point using setColor or setSymbol methods.
