I'm experimenting with swimlane ngx-graph in my app, where users can delete or add nodes. How do I update the graph without refreshing the entire page?
To make changes, utilize the update$ parameter found within the graph options.
In HTML:
<ngx-graph
. . . // Additional settings
[update$]="update$"
. . .
>
In TypeScript:
// Observable for updates
update$: Subject<any> = new Subject();
// Function to update
updateChart(){
this.update$.next(true);
}
After updating your data, remember to call updateChart()
Attempting to alter the data isn't picked up by the change detection system.
this.data = updatedData;
Try spreading the data instead, this way changes will be detected. It's a method that proved successful for me.
this.data = [...updatedData];

Object.assign(this, {data: [...data]});
