I believe what you are referring to is basically a synchronization with graphs.
This could be achievable by turning on the synchronization options for the graph in the dashboard settings tab.
Make sure you have published the other relevant graphs/grids to make this sync work.
Let me know if that helps.
For graph synchronisation across the dashboard you must select the synchronisation option at the same level in the options in dashboard edit mode when selecting the chart as @sandeep_bk mentions.
For information on charts please see the link below:
If you're refering to dynamic charts which change based on inputs in another module please see the link below:
There is also an Anaplan app you can download from the app hub too:
I hope this helps!
