I would like to bind a minimum and maximum value shown on chart to auto adjust y-axes. Auto: True binds the minimum to zero.

min and max properties will appear if you set auto to false

I did see that. The issue is depending on the product running my y-axis needs to auto adjust to the new scope of the chart. For example, my L\* is currently ~40 it could be anywhere in between 0-100 depending on product. Is there a way to tie the minimum & maximum measurement in the chart to the min max values in the y-axis?

So you want the min y to be closer to the min value ? I have no idea how to do that…
