Tooltip is not updating

Hi there,

I am trying to add tooltip in my custom visual. For that I have written follwoing code.

// this if condition is inside update method
if (this.tooltipSettings.show == true) { const tooltipDataItems = []; if (this.tooltipSettings.title != null || this.tooltipSettings.content != null) { tooltipDataItems.push({ "displayName": this.tooltipSettings.title, "value": this.tooltipSettings.content }); }
// adding measure values into array which will be used for show method
// following code will only add measure which are part of tooltip data field tableData.columns.forEach((element, index) => { if (element.roles.tooltipMeasures == true) { tooltipDataItems.push({ "displayName": tableData.columns[index].displayName, "value": tableData.rows[0][index], }); } }); this.root.on("mousemove", (e) => { const mouseX = d3.mouse(this.root.node())[0]; const mouseY = d3.mouse(this.root.node())[1]; this.host.tooltipService.show({ "dataItems": tooltipDataItems, "identities": [], "coordinates": [mouseX, mouseY], "isTouchEvent": true }); }); }

 

 

I am fetching data from one measure field in which I can add multiple measures and pushing them into an array for VisualToolTipDataItem.

The problem I am having is that the tooltip is not updating unless I refresh the page. See following example.

I added Tax Rate in in blank tooltip data field and I am able to see the tooltip as shown below.1.pngThen I added Profit into field but still I can only see Tax Rate on tooltip. See below screen shot2.png

After reloading the whole page, I was able to see both measures on tooltip as shown below.

I used similiar approach to show tooltip in the past and that time it was working but now it is not working properly.

Can anyone tell me what is happening here?

The value property can not contain numbers as per declaration.

To fix this issue you must convert numbers to strings explicitly.
