map shape definition: show x/y coordinate instead of x/y values

dahuang — Thu, 08 Jun 2023 16:44:16 GMT

hi,

I am trying to define a map shape file for a wafer map.

x/y coordinates has different scales: for example, 1 incremental x means 10mm on the wafer; 1 incremental y means 20mm on the wafer.

I have defined a functional map file and all shapes look correct. However, the x/y axis shows actual values in terms of mm.

I would like the map to look the same and still give the correct shape but x/y axis shows coordinates instead of values. Which means that I want x/y axis to be on different scales.

Anyone can help me? Thx.

I suggest you create a pair of new columns with the coordinates derived from the columns of actual values. JMP will not transform values for you automatically in Graph Builder.

hi, Mark

Thx for your suggestions.

A simple axis conversion might not work. For example, if I use x_new = x_old/10, y_new = y_old/20. If shifts my x/y differently, and the shape of my wafer map is not a circle anymore.

I figure out a walk-around by myself. In the defined x/y column, I edit column property: axis to not show default ticks. Instead, I re-define my coordinates as reference lines(not show the line though). This works for me since I don't have too many ordinates to define. If it is more complicated coordinate system, we need extra script to handle this part.

Thx.
