Hi XiaodongLiang,

Visuals are isolated from each other and as such, you can't know what other visuals are doing; just what data your visual has been provided by the main Power BI window into their dataView (which you configure in your capabilities).

If you want your visual to cross-filter others then you will indeed need to create selection IDs for any clickable elements and ensure that the correct IDs are passed out when you call selectionManager.select() on events. This is the documentation you'll need to understand this concept further (if you haven't seen it already), and this contains examples for categorical, matrix and table dataViewMappings.

For your visual to respond to cross-highlight events from other visuals, you will need to enable your the visual for highlighting. Then you will get further info about which data points you are highlighted and you should write code to manage this in your visual - the linked article goes through this with examples too.

If you don't want particular visuals to filter your visual, then edit their interactions in your report to that they don't affect each other.

Good luck,

Daniel

Hi dm-p

 

I also tried using type "any" instead of "Selector" and "SelectorByColumn", as beolw.

 

export interface ISelectionId {
    equals(other: ISelectionId😞 boolean;
    includes(other: ISelectionId, ignoreHighlight?: boolean😞 boolean;
    getKey(): string;
    getSelector(): any;
    getSelectorsByColumn(): any;
    //getSelector(): Selector;
    //getSelectorsByColumn(): SelectorsByColumn;
    hasIdentity(): boolean;
}
 

Then it built without errors, but when I the click event call the select method passing the required selectionID, it doesn't filter the other visuals of the same report.

 

global.visualSelectionManager.select(clickedLngLat.selection, true);
 
Please advise.
 
Thanks in advance.
