add cursor to the waveform graph

[ldragon]

Hi,all,

I want to know how i can add cursors to the waveform graph and display the value,for example,add a cursor to the maximum value point and display the value?

Open the example finder and have a look at "Programmatically Control Cursors.vi".

See how far you get. 🙂

Hi,Altenbach

There are examples with 7.1 as well. One is called simply Cursor.vi. For your example, you just need the Array Min & Max function with a property node of the graph. Something like what is shown below. Of course, you have to first right click on the graph and make the cursor legend visible and create two cursors locked to the plot.
