Custom Layout Live Demo - Hiding Visuals

Hi all,

Looking to see if anyone can help with hiding visuals using checkboxes as per:

https://microsoft.github.io/PowerBI-JavaScript/demo/v2-demo/index.html#

I have it up and running so that the checkbox changing triggers an event which triggers the following code. However the new values for the displaystate is not passed in when using the updatesettings()

What am i missing to enable the visuals to hide.

thanks

//render the values
function renderVisuals() {

// render only if report and visuals initialized
if (!report || !layoutVisuals)
return;

// Get models. models contains enums that can be used

// Filter the visuals list to display only the checked visuals
let checkedVisuals = layoutVisuals.filter(function (visual) { return visual.checked; });
let uncheckedVisuals = layoutVisuals.filter(function (visual) { return visual.unchecked; });
//console.log(layoutVisuals);
//console.log(checkedVisuals);
//console.log(uncheckedVisuals);
let visualsLayout = {};

//for (let i = 0; i < checkedVisuals.length; i++) {
//visualsLayout[uncheckedVisuals[i].name] = {
//displayState: {

// Change the selected visuals display mode to visible
//mode: models.VisualContainerDisplayMode.Hidden
//}
//}
//}

for (let i = 0; i < uncheckedVisuals.length; i++) {
visualsLayout[uncheckedVisuals[i].name] = {
//layout: {
x: 10,
y: 10,
//}
//displayState: {

//Change the selected visuals display mode to visible
//mode: models.VisualContainerDisplayMode.Hidden
//}

}
console.log(visualsLayout[uncheckedVisuals[i].name]);
}
console.log('visualsLayout')
console.log(visualsLayout)
console.log(currentPage)

// Building pagesLayout object
let pagesLayout = {};
pagesLayout[currentPage]= {
defaultlayout: {
displayState: {

// Default display mode for visuals is hidden
mode: models.VisualContainerDisplayMode.Hidden

}

},
visualsLayout: visualsLayout
};

// Building settings object
let settings = {
//pagesLayout: pagesLayout
//filterPaneEnabled: true,
layoutType: models.LayoutType.Custom,
//customLayout: {
//displayOption: models.DisplayOption.FitToPage,
pagesLayout: pagesLayout,
//filterPaneEnabled: true,

//}

};

// Call updateSettings with the new settings object

console.log('refreshing');
console.log(settings);

report.updateSettings(settings)
.catch(function (error) { console.log(error); });

currentPage.getVisuals().then(function (visuals) {
console.log('final')
console.log(visuals);

});
