stanford scale breaks on min: 0

[dastrobu]

Description

When setting the scale to start from 0, it breaks.

scale: {
          min: 0,
          max: 10
     },

Steps to check or reproduce

1. Open https://naver.github.io/billboard.js/demo/#Plugins.StanfordDiagram
2. edit the scale and set to:

        scale: {
          min: 0,
          max: 10000
     }
   

Actual:

Scale has no ticks anymore, and all points are green (no color coding anymore)

Hi @dastrobu, thanks for the report and it was reproducible.
I'll be checking the issue.

I have found that tick uses log scale.
Therefore, it is not reasonable to set domain start as 0, log(0) goes to -Infinity which makes impossible to make ticks.
