Intensity charts are possible in LabWindows8.0.1?

[Roberto83]

I am trying to build an application in LabWindows8.0.1. I have an ultrasonic transducer that produces up to 128 velocity readings (profiles). The time resolution is 10ms. normally, 4096 or 8192 profiles are captured. I want to view all the velocity reading locations (y-axis) vs time (x-axis) having the velocity values color coded. This is possible in LabView but so far I have not been able to do this task in LabWindows8.0.1. The "CREATE" menu does not show intensity charts, only intensity graphs. I can not use intensity graphs because the number of profiles do not fit in the maximum width of the intensity graph.

Hi Roberto83,

It appears nobody has responded to you addressing your question in about a week and I apologize for the no-response.

I wanted to clarify that our Create menu doesn't have an option for Intensity Charts or Intensity Graphs. It does however have a Graph category which consists of Graphs, Strip Charts, and a Digital Graph.  To create an intensity plot, you simply call the PlotIntensity or PlotScaledIntensity functions on a Graph as shown in the intgraph shipping example (<CVI>\samples\userint\ directory). You can also find other intensity plot examples if you open up the NI Example Finder (Help >> Find Examples), switch to the Search tab and type Intensity. This should bring up about 4 examples.

Now of course, you mentioned chart so I am assuming you are requesting for a scrolling intensity plot. It would be nice to have an Intensity Chart as a default control but unfortunately we currently don't have this feature. I would first off encourage you to submit a product suggestion to let us know you wish to see this feature in CVI. 

There have been several customers who have created their own workarounds using Canvas controls and some even using the Strip chart. Check out this forum and this one for some ideas. 

Thanks for posting.

Best Regards,

[Roberto83]

Thank you very much for your information Jonathan. It was very helpful. I will continue working on this issue. The two links you sent me gave me a good idea how to proceed.

Sincerely,

Roberto

I second your comments about using canvases.
I wrote several kinds of 'advanced' strip charts, including vector plots
and intensity charts this way, and using the CanvasScroll function as a
way to move the strip.
