vtyr opened a new issue #3592: Unable to concatenate d3 formula 
URL: https://github.com/apache/incubator-superset/issues/3592
 
 
   - [x] I have checked the superset logs for python stacktraces and included it here as text if any
   - [x] I have reproduced the issue with at least the latest released version of superset
   - [x] I have checked the issue tracker for the same issue and I haven't found one similar
   
   I'm unsure if there is a particular way to format percentages (I've asked around) - but we usually concatenate a symbol on to a d3 formula, such as:
   
   `var numbers = [0.7, 0.75, 0.9, 1.2, 1.21];
   var format = d3.format(".2f")
   numbers.forEach(function(d){
       console.log(format(d)+ "%")
   })`
   
   However, SuperSet does not take code, rather a string to format numbers. This leads to the problem of rounding on percentages when not needed.
   
   ### Superset version
   0.18.5
   
   ### Expected results
   Percentage formatting without rounding to the decimal - ie. 1.2 -> 1.20%
   
   ### Actual results
   Currently unable to have decimal place percentages without rounding (to my knowledge)
   
   ### Steps to reproduce
   .2f returns 1.20
   % returns 12%
