os.system("pause") in pyqtgraph

[Valentina Colmenarez]

Hi! I have a question, regarding an update I need to do on a chart.

I need to update the information of the chart on a secondary window when pressing any key.  For that I'm using the "os.system("pause")" method, which I understand is like the "pause()" method in Matlab. However, the "os.system("pause")" disables the main window of my program. Is there any another method I can use to help me with the current update I need to do?.

Thank you in advance.
