PanOffSet not working anymore

Describe the bug I design control elements in which the user can move my graph using arrow keys. In an earlier version I could move the graph by adding/subtracting values from the current panOffsetY & panOffsetX. However, after upgrading to v. 6.1.0 setting panOffsetX & Y does not change the position anymore.

To Reproduce Steps to reproduce the behavior:

<ngx-graph #graphWrapper [nodes]="hierarchicalGraph.nodes" [links]="hierarchicalGraph.links" [panOffsetY]="panOffsetY" [panOffsetX]="panOffsetX" [zoomLevel]="zoom" [curve]="curve" [view]="" [layoutSettings]="layoutSettings" [scheme]="colorScheme" > ... </ngx-graph>

@ViewChild('graphWrapper') el: NgxGraphInterface;

move(y, x) { this.panOffsetX = this.el.panOffsetX + x; this.panOffsetY = this.el.panOffsetY + y; }

Expected behavior panOffsetX & panOffsetY should update the position of the graph again.

ngx-graph version v. 6.1.0

Thanks.

Hi,

1. I think that keyboard navigation is something that should come from ngx-graph. I started to work on this and hope to release a PR soon.

2. Regrading the pan value, is it related to the pan to node functionality?
