Waveform graph cursor control

[GGLurch]

Hi there,

i am using LabVIEW 6.1 to control a PV module I-V curve generator, which i developed. Part of the control software programming is a long term simulation of actual insulation levels which i collected over 24h. I am loading the information (*.txt file) into an array and display it using a waveform graph. Then i have a cursor in the graph and created a property node (read cursor X-position; cursor is locked to plot) to determine the start point for the simulation within this 24h periode (created array). Now I can determine the startpoint by moving the cursor at the desired start position. LabVIEW is reading the property node fine and the simulation starts at the desired point.

To show the simulation progress i want a second cursor at the point in the graph, which is actually processed right now. I used a second property note (write) and a second cursor but cannot choose the second cursor specifically in the write property note to control the X-position when locked to plot. Thus, nothing is happening with the second cursor. Also, the first cursor stays at its position. What am I writing where with the write property node? How can i control the X-position of a specific cursor?

By the way: How do i remove a cursor once it is activated? I never get rid of cursors which i have activated somehow.

Thxs, i appreciate any help.

Hi GG,

On the property node, when you select the cursor option, there an option above this one which is named "active cursor".
This permit you to select which cursor you are working with.

Here is an example of use with the active cursor option.

Does this resolve your problem?

Great, works perfectly! Thanks a lot.
