Hi,
If you are using the pie chart widget you can add configurations and Layout in the tab Advanced. Don’t forget to set “Mode” to “Advanced”. If you do not use this, i would recommend to use it. In the chart properties you can change from pie to doughnut.
Hi,
You should add this part to the data to get the hole. The number will determine how big or small the hole will be. I hope this helps.
, "type": "pie",
"hole": "0.6"
