Cursor to follow data points on waveform graph

[David Carty]

I am using LabVIEW to record spectra, which are then displayed on a waveform graph. It is essential that line positions can be found and I would like to do this using a cursor of some kind to scan along and folow the data points whilst displaying the data coordinate. How can this be done?

You could display cursor (right click on the graph, and enable the cursor
legend). Before, you just have to click (left) on the little padlock and
choose the good option
('attache au point' or 'verouille au trace' in my french version of LV6.0.2)

Hi David,
right click on the graph, and go to visible items : cursor legend.
From here you can select which plot to attach the cursor to, and also
snap to point or lock to plot). The cursor needs a name to be
activated.
Have a look in the help files under cursors for more information, and
you can also use methods and properties to do this programatically.
