Making Deneb dynamic

I added the data to the model and set it as a percentage type. The same with the measure.

The key thing is that percentages will be added to a Deneb visual as a decimal value, so to make this work with the template, you will need to:

1. Modify my suggestion to multiply by 100 to get a number between 1 and 100 rather than 0 and 1, e.g.:
   

   {
       "name": "percent",
       "update": "data('dataset')[0]['_Percentage'] * 100"
   }​

2. Because this might result in a floating point value with many decimal places, modify the text mark's text property to use a format function call to fix it to 2 decimal places, e.g.:
   

   {
       "type": "text",
       "data": [{}],
       "encode": {
           "update": {
               "text": {
                   "signal": "format(percent, '.2f') + '%'"
               },
               ...
           }​

Note that these are minimal changes against the original template. If you have a format string against your model, you could probably use the technique in step 1 to get the _Percentage__format field that Deneb creates for measures into an additional signal and substitute that into step 2 rather than do the formating work manually, or use the pbiFormat function in Deneb to use a Power BI format string. However the above approach will work as you intend it to:

I've added this to a report and attached it so you can confirm it works and investigate the solution yourself. Changes are on lines 14 and 175 of the specification.
