Windows XP Professional with Python 2.5 installed (pywin32 build 210) - came with dSPACE software package
Downloaded and installed matplotlib-0.99.1.win32-py2.5.exe from sourceforge.net Downloaded and installed numpy-1.4.0-win32-superpack-python2.5.exe from sourceforge.net Executing the following simple "log plot" script within PythonWin: from matplotlib import pylab # Create some artificial data. test_frequency = [1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20] test_results = [-0.2, -0.7, -1.0, -1.5, -2.0, -2.5, -3.0, -3.5, -4, -5, -6, -7.1, -8, -9, -10, -11, -12, -15, -20, -25] spec_frequency = [6, 8] spec_results = [-3.0, -3.0] # Plot figure = pylab.subplot(111) figure.semilogx() figure.scatter(test_frequency, test_results, s=20, c='b', marker='s', edgecolors='none') figure.scatter(spec_frequency, spec_results, s=40, c='g', marker='s', edgecolors='none') figure.grid(True) figure.set_xlabel(r"Frequency (Hz)", fontsize = 12) figure.set_ylabel(r"Actuator Response (db)", fontsize = 12) figure.figure.savefig('log_plot') figure.figure.show() Plots a figure on the screen that looks correct, then the following error (when I click OK, PythonWin closes) Any advice would be appreciated. Maybe it's an installation or setup issue, but I'm pretty knew to Python programming and don't know how to debug this. Lee Boger
