A worksheet that worked fine under sage 3.4.2 and 4.0.alpha0 fails under 4.0rc0. The whole sheet can be seen at sagenb.org: http://sagenb.org/home/pub/541 A relevant minimal example is: {{{id=3| import matplotlib.pyplot as pyplot /// }}} {{{id=0| RealNumber=float; Integer=int A=3202.6427147395325 B=2.7068484110275158e-05 fit(x)= A + B * x Xfit=[0, 800000000] Yfit=[fit(0), fit(800000000)] /// }}} {{{id=1| P2=pyplot.plot(Xfit, Yfit, 'b') /// Traceback (most recent call last): File "<stdin>", line 1, in <module> File "/home/kwh/.sage/sage_notebook/worksheets/KevinHorton/22/code/ 14.py", line 6, in <module> exec compile(ur'P2=pyplot.plot(Xfit, Yfit, \u0027b\u0027)' + '\n', '', 'single') File "/opt/sage-4.0.rc0/local/lib/python2.5/site-packages/Jinja-1.2- py2.5-linux-i686.egg/", line 1, in <module> File "/opt/sage-4.0.rc0/local/lib/python2.5/site-packages/ matplotlib/pyplot.py", line 2118, in plot ret = gca().plot(*args, **kwargs) File "/opt/sage-4.0.rc0/local/lib/python2.5/site-packages/ matplotlib/axes.py", line 3348, in plot for line in self._get_lines(*args, **kwargs): File "/opt/sage-4.0.rc0/local/lib/python2.5/site-packages/ matplotlib/axes.py", line 404, in _grab_next_args for seg in self._plot_3_args(remaining, **kwargs): File "/opt/sage-4.0.rc0/local/lib/python2.5/site-packages/ matplotlib/axes.py", line 343, in _plot_3_args x, y, multicol = self._xy_from_xy(x, y) File "/opt/sage-4.0.rc0/local/lib/python2.5/site-packages/ matplotlib/axes.py", line 218, in _xy_from_xy by = self.axes.yaxis.update_units(y) File "/opt/sage-4.0.rc0/local/lib/python2.5/site-packages/ matplotlib/axis.py", line 969, in update_units converter = munits.registry.get_converter(data) File "/opt/sage-4.0.rc0/local/lib/python2.5/site-packages/ matplotlib/units.py", line 139, in get_converter converter = self.get_converter( thisx ) File "/opt/sage-4.0.rc0/local/lib/python2.5/site-packages/ matplotlib/units.py", line 138, in get_converter for thisx in x: TypeError: 'sage.symbolic.expression.Expression' object is not iterable }}} Is this an expected result due to a change in sage-4.0.rc0? If so, I'd appreciate any hints on how I need to modify my code.
