I have a problem accessing my "_groups" property with the following code:
function mouseDate(scale){
var g = d3.select("#group")._groups[0][0]
var x0 = scale.invert(d3.mouse(g)[0]);
console.log(x0);
}
Result of my console.log:
Selection {_groups: Array(1), _parents: Array(1)}
_groups: Array(1)
0: Array(1)
0: g#group
When I compile the code I have the following error :
D:/Documents/starter-propre-angular4/src/app/pages/graphe-page/graphe.page.ts (782,32): Property '_groups' does not exist on type 'Selection<BaseType, {}, HTMLElement, any>'.
So my question is: Is there a solution to get the information in "_groups" all year round knowing that I am evolving into TypeScript using d3js
