10.1.1. Opening plot windowsΒΆ

PyOPUS provides a wrapper around the MatPlotLib plotting library. The wrapper runs the code that refreshes the windows in a separate thread so that the windows remain active during computation. After a short prologue that sets up the windows the user can plot within those windows using the MatPlotLib API. The resulting figures can be exported in several file formats.

import pyopus.plotter as pyopl

if __name__ == '__main__':
	# Initialize gui thread. The thread exits when control window is closed. 
	# If the GUI thread was running before init(), 
	# there might be some plot windows around. 
	# Close them. 
	# Create a figure with default size (matplotlibrc). 
	print("pyopl.figure() returned: "+str(f0))
	# Create a figure with 400x300 pixels, 100dpi. This gives a 4x3 inch image. 
	f1=pyopl.figure(windowTitle="Window title 1", figpx=(400,300), dpi=100)	
	print("pyopl.figure() returned: "+str(f1))
	# Change window title. 
	pyopl.title(f1, "Changed window title 2")
	# Close a figure. 
	# pyopl.close(f1)
	# Close all figures
	# pyopl.close()
	# Show/hide (True/False) figure 
	# pyopl.showFigure(f0, False)
	# pyopl.showFigure(f0, True)
	# Raise figure / active figure 
	# pyopl.raiseFigure(f0)
	# Wait for the user to close the GUI Control Window.
