Map component does not render correctly long distances

Open elizarp opened this issue 9 months ago • 0 comments

  • NeoDash version: v2.4.9-labs

  • Neo4j Database version: Aura Sandbox

  • Expected behavior If we consider the distance between Sao Paulo (Brazil) and Auckland (NZ) and compare this distance with the distance between Santiago (Chile) and Auckland (NZ), the first one if greater. However, the map component is rendering the relationship between the cities in the "wrong" direction.

I used point.distance to calculate the distances.

Distance Sao Paulo > Auckland: 12,033,465.188858354 (greater) Distance Santiago > Auckland: 9,680,687.387294235

  • Actual behavior I built the Cypher below to show the scenario
WITH 
  point({longitude: -70.673676, latitude: -33.447487}) AS pointSantiago,
  point({longitude: 174.763336, latitude: -36.848461}) AS pointAuckland,
  point({longitude: -46.6388 , latitude: -23.5489}) AS pointSaoPaulo
CALL apoc.create.vNode(['City'],{name:"Santiago",geo: pointSantiago}) YIELD node as nodeSantiago
CALL apoc.create.vNode(['City'],{name: "Auckland", geo: pointAuckland}) YIELD node as nodeAuckland
CALL apoc.create.vNode(['City'],{name: "Sao Paulo", geo: pointSaoPaulo}) YIELD node as nodeSaoPaulo
CALL apoc.create.vRelationship(nodeSantiago,'DISTANCE',{distance:point.distance(pointSantiago, pointAuckland) },nodeAuckland) YIELD rel as relS_A
CALL apoc.create.vRelationship(nodeSaoPaulo,'DISTANCE',{distance:point.distance(pointSaoPaulo, pointAuckland) },nodeAuckland) YIELD rel as relSP_A
RETURN nodeSantiago,nodeAuckland,nodeSaoPaulo,relS_A, relSP_A;
