Hello!

First of all, thank you all for your work. I'm using ECharts right now in my 
own project and want to let you know how much I appreciate making your work 
available to everyone.
If anybody has the time, I was wondering if you would be willing to help me 
answer a question about axis scaling.

Right now, I'm attempting to implement a Weibull plot, which has a custom 
y-axis scale:

 *   y-axis: ln(-ln(1-f(t)))

https://www.itl.nist.gov/div898/handbook/eda/section3/weibplot.htm

Is there a way to create an axis with this scale in ECharts? I realize that the 
options available right now for an axis scale are "value", "log", 
"categorical", and "time", so it appears I would need some workaround.

For example, I am wondering if it would be possible to plot ln(-ln(1-f(t)) on a 
"value" scale, but to transform the axis ticks so that for a given y-value 
ln(-ln(1-f(t))), the respective tick on the y-axis is f(t) - this would, in 
essence, implement a custom scale. It looks like this is not possible, but I 
thought I would reach out in case there might be some way of achieving this.

Thank you for your time,
Mitch
