LAUNCHXL-F280049C: gui composer stand-alone app can't display graph

Hello,

Likely the variable binding is not correct. Can you export and share your GC project?

Thanks

tt3.zip

thank you!

Thanks. It doesn't look like you defined any lines for the plot and bound them.

Have you seen the help:

when I run the example in dev.ti.com/gc, it can display data graph,

Can you point me to this example?

Thank you Ki , I have seen the index.html#gc-widget-plot help  , it's demo use gc-model-streaming , I think it use USB-UART communication . I use xds110 , the way of bind data look like

when program is running in cloud  it can plot data line. the DSP pro'gram is TI demo 'dual_axis_servo_drive_fcl_qep_f28004x' .

sorry, I was wrong. You are correct, everything looks good and I can run in in GC and it works fine but not when I run as standalone app. I escalated this to engineering and they are investigating. Sorry for the delay

It's nothing , I am going to Measuring vibration waveform of 10Hz , but I find it refresh very slow, I don't know the gui sample frequency.

After discussion with the GUI Composer engeineers, it looks like binding to point is not officially supported and that streaming mode needs to be used. The fact that you got it to work in GC online was actually surprising and likely just a coincidence. They are trying to confirm this but so far it appears to be the case.

Thanks

thank you Ki , I think the gui is convenient for debug program. It save my time to program demo screen.
