Rif.: RS232 values to graph

[MajklS]

Hi,

yes you're right, i didn't put the value in the box.
Thank you.

However, I don't get anything on the serial port. Graphics still run without having the simulation turned on.

Mind to share your current VI to help us to help you?

How does a "graphics still run" when you "don't get anything on the serial port"?

Don't you think it would help you to learn some LabVIEW basics?

Hello GerdW,

Right now, when I have an RS232 serial port connected and sending data, nothing is displayed.
The graph is running, but the rendering is zero.

Yes, you're right with the basics, I'm currently studying one book.

Why are your chart terminals outside the while loop?

That means they don't get any data until the loop ends.  Then it will only get the last value, and it will probably look like nothing since a single point doesn't show up by default on a waveform chart.

I would recommend you learn more about LabVIEW from here. How to Learn LV

Oh, good knowledge, thank you for your advice. I put 2 graphs in a loop, but how does it know I want to render RdData [0]?

Thank you for the link to Labview tutorial.

Do you even read the answers you got for your questions?

To index an array element (like RdData[0]…) you should use the IndexArray function!
