# Graph Y-axis

Use the Part chooser to target the part you want to measure. Select the targeted part's property to be measured from the list in the Property chooser.

Key points:

- If one or more traces have already been set up, the list will include all the graphable properties of the parts that have been targeted.
- If no traces have been set up, the list will include all the graphable properties of all the parts in the scene.
- If one of the parts to be traced does not have the chosen property, the trace Part chooser is highlighted in red and no trace will appear.
