[Matplotlib-users] Why Is This Code Failing?

[Rich S. <rsh...@ap...>]

   Here is the relevant code fragment:

 	for i in range(1, compList[0][16]):
           pylab.hold(True)
           if compList[0][4] == 'Decay S-Curve':
             testFunctions.zCurve(compList[0][10],compList[0][9])
           elif compList[0][4] == 'Bell Curve':
             testFunctions.gaussCurve(compList[0][14],compList[0][14])
           elif compList[0][4] == 'Growth S-Curve':
             testFunctions.sCurve(compList[0][8],compList[0][11])
           elif compList[0][4] == 'Beta':
 	    testFunctions.betaCurve(compList[0][13],compList[0][12],compList[0][14])
           elif compList[0][4] == 'Data':
             continue
           elif compList[0][4] == 'Linear Increasing':
             testFunctions.linearIncrCurve(compList[0][8],compList[0][11])
           elif compList[0][4] == 'Linear Decreasing':
             testFunctions.linearDecrCurve(compList[0][10],compList[0][9])
           elif compList[0][4] == 'Left Shoulder':
 	    testFunctions.leftShoulderCurve(compList[0][10],compList[0][11],compList[0][9])
           elif compList[0][4] == 'Trapezoid':
 	    testFunctions.trapezoidCurve(compList[0][8],compList[0][10],compList[0][11],compList[0][9])
           elif compList[0][4] == 'Right Shoulder':
 	    testFunctions.rightShoulderCurve(compList[0][8],compList[0][10],compList[0][11])
           elif compList[0][4] == 'Triangle':
 	    testFunctions.triangleCurve(compList[0][8],compList[0][13],compList[0][9])
           elif compList[0][4] == 'Singleton':
             testFunctions.singletonCurve(compList[0][13],compList[0][14])
           elif compList[0][4] == 'Rectangle':
 	    testFunctions.rectangleCurve(compList[0][8],compList[0][10],compList[0][11],compList[0][9])
           elif compList[0][4] == 'Outcome':
             testFunctions.outcomeCurve()
         pylab.savefig(curVar+'.png')
         pylab.hold()

   When it runs in the test script the first curve is plotted in a matplotlib
window and the program pauses until I close that window by clicking on the
upper right button on the frame. Then this traceback is displayed:

Traceback (most recent call last):
   File "termset-test-data.py", line 391, in ?
     testCode()
   File "termset-test-data.py", line 388, in testCode
     pylab.hold()
   File "/usr/lib/python2.4/site-packages/matplotlib/pyplot.py", line 334, in
hold
     rc('axes', hold=b)
   File "/usr/lib/python2.4/site-packages/matplotlib/pyplot.py", line 74, in
rc
     matplotlib.rc(*args, **kwargs)
   File "/usr/lib/python2.4/site-packages/matplotlib/__init__.py", line 712,
in rc
     rcParams[key] = v
   File "/usr/lib/python2.4/site-packages/matplotlib/__init__.py", line 552,
in __setitem__
     cval = self.validate[key](val)
   File "/usr/lib/python2.4/site-packages/matplotlib/rcsetup.py", line 43, in
validate_bool
     raise ValueError('Could not convert "%s" to boolean' % b)
ValueError: Could not convert "None" to boolean

   What I want is to have all curves from 1 to the maximum number (in
compList[0][16]) plotted on the same set of axes, then save that figure and
go on to the next one.

   Is my problem an indentation error at the end of the IF...ELIF tests?

TIA,

Rich
