I couldn't find any keyword like 'grid' in the help document of 'plot()' <function sage.plot.plot.plot="">, and hence I tried NUMERICAL PLOTTING: but nothing came out... OK, how can I check if SAGE can call Matplotlib in my OS (openSuSE 12.3) correctly? I have installed and updated 'matplotlib' for Python 2.7 via YaST2. Thanks in advance! |
