a numeric vector. |
unit |
supported units, only "mm", "cm", "inches". |
sector.index |
index for the sector where the conversion is applied. |
track.index |
index for the track where the conversion is applied. |
h |
since the width of the cell is not identical from the top to the bottom in the cell, the position on y direction needs to be specified. By default it is at the middle point on y-axis. |
A vector of numeric values which are measured in the specified data coordinate.
