why waveform chart does not appear when "run"?

[GoncaloPT]

Hi everyone,

I'm new to LV and I'm trying to build a VI to read 4 pressure transductor channels and dispose data on a waveform chart and on a excel table...

In my VI everything is running well, however it can´t write the charts in "real-time" on my waveform chart...why?

Another issue is that I don't know how to automatically write the waveform and the data to an excel file when the run time elapses...

Could anyone show me how to solve this issues?

Best regards

GoncaloPT,

First of all, welcome to LabVIEW, you've made a solid start. I've made a few small changes and added some comments explaining why I think they might help you.

I picked the simplest way to export to Excel but you have many options.  I think this document is the best place to start learning about them (mostly because I wrote it :)) - http://zone.ni.com/devzone/cda/pub/p/id/1339

Good luck!

Thanks a lot Simon.

I didn´t try to run the program because today is holiday in Portugal and I'm not at work. But I took a look to the code you sent me and it seems to me that is all i needed do continue my project.

Tomorrow i'll brief you how it worked.

Thanks again and best regards from Portugal 😉

Hi again Simon,

could you please convert me the VI you sent me to LV version 10?

You sent it to me in version 11...

Thanks

Another issue is that, now i can't lock my waveform chart x-axis values...when i click "run" the x-axis changes its values to a huge number instead 0 to 300...
