In order to get the cursor position of the Waveform Graph, you may use the Cursor List property.
- On the block diagram of your VI, right click the Waveform Graph and select Create » Reference, and place the created Reference Node on the block diagram.
- Place a Property Node on the block diagram and connect it to the Waveform Graph Reference Node.
- From the dropdown list of the Property Node, select Cursor List. The Cursor List is an array of all the cursors on the Waveform Graph. Each cursor is represented by a cluster of the X and Y position data.
- Connect the output of the Cursor List to a For Loop to process the cursors one by one.
- Place an Unbundle By Name node in the For Loop, and connect it to the Cursor List cluster.
- Drag the bottom frame of the Unbundle By Name node to make room for two outputs. Click on each output and select Position » X, and Position » Y. You can now choose to output the positions as arrays of all the cursor X and Y positions.
