Waterfall Plots

[u2npm]

Hi All,

Is there a way to produce live data monitoring waterfall plot in FlexLogger?  New to NI and FlexLogger nearly fits my application. Thanks a lot.

Can you share more about your application and the importance of the waterfall plot for that use case?

Hi Santhosh,

I am using waterfall plots for complex (or simple) vibration diagnostics, I find them useful to understand the spectrum over a period of time.  ICP accelerometers, into a 9230 or 9232 card, looking to see if flexlogger can provide this in addition to its standard form factor.  I'm a little vague on what applications/plugins are able to do.

Thanks,

Chris

Unfortunately, FlexLogger doesn't support waterfall plots and cannot be extended directly to add more visualizations.

FlexLogger Addin SDK allows you to implement custom in-line calculations and acquire data from NI hardware supported by FlexLogger and third-party hardware but not custom UI.

FlexLogger features a Plug-in Development Kit that you can use to add such functionality to FlexLogger.
You can download it at FlexLogger Plug-In Development Kit Download - NI

You program the plugin in LabVIEW. Here is the manual to give you an idea of what is involved:
FlexLogger Plug-in Development Kit User Manual - NI

To give you an example of what is possible, I am attaching a plugin that displays a external window showing the spectrogram of a channel.
This should be very close to what you want to do.

We will soon create a github repo with some plugins that the community will be able to contribute to and use.
More on this coming soon!

Please let me know if you have any questions.

We could also provide our services to help complete this as a plug-in to FlexLogger. We have done other plug-ins in the past.

you can send me an email at vcarpentier (at) neosoft (dot) ca

All the best,

@u2npm, would an implementation as shown in this post work for you?
