Can somebody please show me, how to enable multi touch zoom in Genogram (link & code from gojs site)
ctrl++ is working fine, but not multi touch
I want to see gengram in mobile with zoom and pan option, in addition I just want select node option for showing extra details of node. I do not want node or link moving or new link creation.
I tried for many days but could not do it.
I read about standardPinchZoomStart but do not know how to use it. can somebody give example code.
