You can simulate this problem with a syntax mistake  however   matplotlib inline won t resolve the issue    First an example of the right way to create a plot  Everything works as expected with the imports and magic that eNord9 supplied    df randNumbers1   pd DataFrame np random randint 0 100 size  100  6    columns list  ABCDEF     df randNumbers1 ix     A   B    plot kde     However  by leaving the    off the end of the plot type you receive a somewhat ambiguous non-error   Erronious code   df randNumbers1 ix     A   B    plot kde   Example error    lt bound method FramePlotMethods kde of  lt pandas tools plotting FramePlotMethods object at 0x000001DDAF029588 gt  gt    Other than this one line message  there is no stack trace or other obvious reason to think you made a syntax error  The plot doesn t print

I have to agree with foobarbecue  I don t have enough recs to be able to simply insert a comment under his post    It s now recommended that python notebook isn t started wit the argument --pylab  and according to Fernando Perez  creator of ipythonnb   matplotlib inline should be the initial notebook command   See here  http   nbviewer ipython org github ipython ipython blob 1 x examples notebooks Part 203 20- 20Plotting 20with 20Matplotlib ipynb

I had the same problem when I was running the plotting commands in separate cells in Jupyter   In  1     matplotlib inline          import matplotlib          import matplotlib pyplot as plt          import numpy as np In  2    x   np array  1  3  4            y   np array  1  5  3   In  3    fig   plt figure             lt Figure size 432x288 with 0 Axes gt                        this might be the problem In  4    ax   fig add subplot 1  1  1  In  5    ax scatter x  y  Out 5     lt matplotlib collections PathCollection at 0x12341234 gt     CAN T SEE ANY PLOT    In  6    plt show                                                 STILL CAN T SEE IT      The problem was solved by merging the plotting commands into a single cell   In  1     matplotlib inline          import matplotlib          import matplotlib pyplot as plt          import numpy as np In  2    x   np array  1  3  4            y   np array  1  5  3   In  3    fig   plt figure            ax   fig add subplot 1  1  1           ax scatter x  y  Out 3     lt matplotlib collections PathCollection at 0x12341234 gt             AND HERE APPEARS THE PLOT AS DESIRED

If your matplotlib version is above 1 4  it is also possible to use  IPython 3 x and above   matplotlib notebook  import matplotlib pyplot as plt   older versions   matplotlib nbagg  import matplotlib pyplot as plt   Both will activate the nbagg backend  which enables interactivity

I used  matplotlib inline in the first cell of the notebook and it works  I think you should try    matplotlib inline  import matplotlib import numpy as np import matplotlib pyplot as plt   You can also always start all your IPython kernels in inline mode by default by setting the following config options in your config files   c IPKernelApp matplotlib  lt CaselessStrEnum gt    Default  None   Choices    auto    gtk    gtk3    inline    nbagg    notebook    osx    qt    qt4    qt5    tk    wx     Configure matplotlib for interactive use with the default matplotlib backend
