Is it true that the limit of the graph shown in the report VI is only limited to 0.1?

Hi Philips,

I want the report to show the relative time to the beginning of the data collection.

Thanks.

Hi Sammmy,

Without your VI it's going to be a little hard to tell you exactly what to do, but what you want to make sure is that you are passing relative data and not absolute data to the Report VI. If you're passing a Waveform Datatype, make sure that the "t0" timestamp is 1904 which means that the time is relative.

Hi Philip,

Hope you have a smashing new year ahead!

I'm faced with 2 difficulties at this moment.

1) Attached is my VI. I still can't reflect the relative time in my html report.

2) I'm using the USB-6009 DAQ card to acquire 2 signals, the voltage from the current probe and the voltage from the accelerometer. I want to show the 2 waveforms separately and perfomed different analysis on the signals. But the data coming out from the DAQ assistant is a combination of the 2 signals. How can I separate them? Use another DAQ assistant for the other signal?

Please advice me on this.

Thank you.

Regards,

Sammmy

Can some kind souls please help me with this problems?

Hi Philips,

I think I had uploaded the wrong VI in my previous thread.

This is the right one. Sorry for the time wasted.

You can use the Split Signals function.

Also, try to clean up your VI's wiring a bit. You've got the same wire exiting the while loop in 3 different locations, some go backwards, and some are hidden under other wires or functions. The shipping documentation comes with a style guide that you should read. A properly laid out diagram will make things much simpler to debug and maintain.

Hey Dennis,

Thanks for your advice!

I still have the problem of showing the relative time in my generated HTML report.

The time reflected in the report is dated all the way back from 1904 till now.

Sammmy,

I tested a few things and was able to replicate your problem.  It seems that somewhere along the line your dynamic data signal that you are passing to the Report Express VI is being converted to a waveform with something other than 0 as the t0.  If this happens you will only see those large numbers which as Philip pointed represents the date and time.  If you convert the dynamic signal to a waveform and then set the t0 to 0 you should be able to get only the relative time in your HTML report.  Here is a small example of this using the Simulate Signal Express VI and the Report Express VI.  To create the empty time stamp right-click on the Build Waveform t0 input terminal and select Create >> Constant.



Hope this helps!

Hi Andy,

Thanks for your help!

It works but why is it that the generated html report shows the graph with the y-axis either in 0 or 1?

The attached picture is a sample of my report.

Attached is also my VI.

Sammy,

What do you expect the y-axis to be?  Does the data not go from 0 to 1?
