Customize Tooltip for Stacked bar chart

chloepedicone 

Hi, this can be done with Custom tooltip page. In your case you may just need to place a Card Visual on the tooltip.

As an example, assuming you have a Stacked bar chart like below and you only need 'No. of Calls' apprearing on your Tooltip. 

Instead of using the default tooltip, create a new page and set its 'Canvas Type' to 'Tooltip' in the page settings.

On this tooltip page, place a 'Card visual' and add your measure (e.g., No. of Calls) to it. You can format the card to look clean and compact so it displays well as a tooltip.

Then, go back to your original page with the stacked bar chart. In the 'Visual' - 'Tooltip' settings, choose your custom tooltip page. And that’s it, now only ‘No. of Calls’ will show in the tooltip when hovering over the bars.
