plot dynamic data with time stamp

Hi All

 

I would like to create a plot of dynamic data, (Voltage readings taken with an In 6008) versus time.

 

When the loop starts taking voltage data I would to plot the data versus elapsed time. Voltage versus time elapsed. I have read many examples and tried for many hours to get this to work.

 

Please help!

Hi Mike,

 

Are you using a Waveform Chart? A chart will continuously plot the data versus time as it is acquired. Try right clicking on the x-axis and selecting Properties>> Display Format. Here you can change the way time is displayed on the x-axis. You can also adjust the way the data is displayed by right clicking and going to Properties>>Appearance>>Update Mode.

 

I hope that helps! If not, can you indicate what specifically you have set up in your code and how the result is different from the plot you would prefer to create.

 

Thanks,

Hi !

 

I want to plot dynamic temparature data. I have 8 sensors to acquire signal through USB. I want to plot  the best increasing signals amaong them. How Can I do this?

 

I can plot all of them togather but not getting the clue how could I choose which has the increaseing profile and discard those which does not have any temarature increase.

 

 

Should I need to store the data first and then do some gradient masurement on those?

 

 

But still do not know to make gradient masurement on dynamically acquiring data..

 

Thanks

Hi Hassan, 

 

Since this is a two year old thread, you would probably be best served by creating a new forum thread. This will help the forum community locate your question, and hopefully provide beneficial advice on the matter.

 

I hope this helps.
