No line graph on macOS

[JohannesMaierhofer]

Hi and thanks for this great tool. I'm working on macOS, python 3.11. Everything works quite smooth but I can't get a graph line in the visualization. I can measure and save the data as intended.

My minimal working example is:

import LDAQ

acq_serial = LDAQ.serial_communication.SerialAcquisitionSimple(port="/dev/cu.usbmodem1101", baudrate=115200,
                                                acquisition_name="arduino",
                                                delimiter=",",
                                                start_character= "",
                                                end_character  = "\r\n",
                                                sample_rate=None,
                                                channel_names=None)

vis = LDAQ.Visualization(refresh_rate=100, max_points_to_refresh=1e4, sequential_plot_updates=True)

vis.add_lines((0, 0), source="arduino", channels=0)
vis.add_lines((1, 0), source="arduino", channels=1)

vis.config_subplot((0, 0), xlim=None, ylim=(0, 5), axis_style='linear')
vis.config_subplot((1, 0), xlim=(0, 1), ylim=(0, 5), axis_style='linear')

ldaq = LDAQ.Core(acquisitions=[acq_serial],visualization=vis)

ldaq.run(measurement_duration=10)

Thank you for trying out our package!

I've tried running your minimal script on macOS, but I've changed the code slightly to accommodate for my arduino (changed the y limits, port and baudrate). The code was the following:

import LDAQ
acq_serial = LDAQ.serial_communication.SerialAcquisitionSimple(port="/dev/tty.usbmodem142301", baudrate=9600, # changed this line
                                                acquisition_name="arduino",
                                                delimiter=",",
                                                start_character= "",
                                                end_character  = "\r\n",
                                                sample_rate=None,
                                                channel_names=None)

vis = LDAQ.Visualization(refresh_rate=100, max_points_to_refresh=1e4, sequential_plot_updates=True)

vis.add_lines((0, 0), source="arduino", channels=0)
vis.add_lines((1, 0), source="arduino", channels=1)

vis.config_subplot((0, 0), xlim=None, ylim=(0, 5000), axis_style='linear')   # changed the limits
vis.config_subplot((1, 0), xlim=(0, 1), ylim=(0, 5000), axis_style='linear') # changed the limits

ldaq = LDAQ.Core(acquisitions=[acq_serial],visualization=vis)

ldaq.run(measurement_duration=10)

print( ldaq.get_measurement_dict() )

The upper code worked for me, and I can see the lines of the channels. Do you get any errors or warnings while running the script? If so, a traceback would be appreciated!

[JohannesMaierhofer]

Thanks for reaching out. I tried with a super simple dummy microcontroller code. There, it works. Probably I have problems with formatting the output of my measurement data.

I get a terminal print: Unknown property align But I don't know if it affects the functionality.

Is it intended that the GUI closes right after finishing the measurement?

[TKosir]

The warning you get should not affect the functionality, we will fix the warning in future releases.

You can disable the auto closing of the GUI by specifying 'autoclose=False' in the ldaq.run() method.
