Is there a way to call a widget's clear selection from a widget's custom script?

I want to be able to do what the "Clear Selection" button does on a widget that "Affects Dashboard filters", programmatically through custom JavaScript.

I'd like to make this function call work but it doesn't.

var W = 
    prism.activeDashboard.widgets.$$widgets.find( (x) => { return (x.title == "Bar Chart Widget"); } );

prism.$command.execute('dashboard.commands.clearWidgetSelection', 
                       {$scope: prism.user}, 
                       {dashboard: dashboard, widget: W});

  Hey Barry,

  Instead of trying to click the button progmatically, it may be easier to just replicate the effects. 

   

  I would through prism interate through your dashboard filters and set the filter jaql for all to be

  {
  "explicit": false,
  "multiSelection": true,
  "all": true
  }
  
  Which is basically just the include all filter. 

  Would this work?

  Hi Nathan Giusti,

  I'm trying to only clear one specific filter that is controlled by a bar chart widget in this case.

  I can see that the 'Clear Selection' button ultimately calls this command and I think I'm close except that I am passing in the wrong argument(s).

  prism.$command.execute('dashboard.commands.clearWidgetSelection', 
                         {$scope: prism.user}, 
                         {dashboard: dashboard, widget: W});

   

  I've also come up with this:

  if (0 < Widget.metadata.selectionData().length) {
  	Widget.metadata.clearSelection();
  }
