Graph2d | Groups Example

+
+ This example shows the groups visibility functionality within Graph2d. Groups have their own visibility option. By using this, + all graph2d instances using those groups would show or hide that group. If you have multiple instances sharing the same data and groups, + you can use the groups.visibility option to set it on an instance level. The graphs below all share the same groups, items and initial options. + We then use a setOptions like so: + + +

+                visibility:{
