editing analog waveforms (amplititude)using mouse

coolraj — Wed, 21 Apr 2004 11:40:10 GMT

I want to edit arbitary analog waveforms graphically using a mouse,for example to edit the amplitude of a waveform irregularly just by drawing with a mouse.I tried the analog waveform editor but it doesn't seem to have such facility.Is there anyother tool which I can use ??
Thanks in Advance

Hi,
I'm currently trying to develop such a graph.
Here's what I've already done. It's an LV7.0 version becauce of the use of dynamic event registration. There is still lots of things to develop on it but it already works as is.
Sorry but the comments are in French 🙂

Hope this helps !

Hi Julien !
I'm trying to import some data from txt file ( time and amplititude)I've imported the data but I'm struggling a bit to bring it into the table that you've created as a cluster , is it possible to set the inputs as two seperate float inputs.
Thanks in advance
Rajan

Hi Rajan,
Here's an example of how to import data from a txt file and create an XY Graph (same kind of graph as in my first attachement).
I join a txt file found yesterday somewhere in this forum just to have a little bit of data to process.

Hope this helps !

Cheers mate !
That definately helped ,I'm very please with your hand in this.By the way have you come across any other graphical waveform editing tool where I can adjust the amplitude of analog waveforms on a timeline basis ,with functions like copy & paste,adding noise and things like that.If so please let me know even if it's a different program from labview.Cos a client of mine doesn't want to do editing the hard way.He wants to edit the waveform by drawing.I would be very grateful for your advice.
Thanks
Rajan

In LabVIEW's examples -> Key word : Waveforms -> Lots of VI's could be intersting for you (Noise waveforms and PS Density.vi for instance).

Feel free to refer as much as possible to those examples. They often show you how to develop things.
That's all I can tell you

Hope this helps !
