Hi, I don’t think that works, as the second axis has a different scaling. E.g. x-axis2 is scaling of factor of 2 of xaxis1.
example one scale kelvin, one degC, or one scale mm, other meters. in my case I need to show meters, and then number of adjacent machines which are positioned along the meter length, which happen to be 2m wide. so the graph can let users see meter mark, or which machine id a point is at.
