How to hide <matplotlib.lines.Line2D> in IPython notebook
Solution 1
You can use a semi-colon ;
to end the line. This suppresses the unwanted output when generating plots:
plt.plot(I,'o');
In general, using a semi-colon stops IPython from printing any output value from that line of a code block. For example, the executing the cell containing the code 1+1;
would not output 2
.
An alternative way would be to bind a variable to the plot:
_ = plt.plot(a)
This way, IPython only shows you the plots and the name _
is bound to the unwanted output.
Solution 2
Another way is to just write plt.show()
at the end of your drawing code. It would take less symbols to type if you're generating many subplots and/or drawing many plots on a single subplot.

I am plotting a NumPy array of values,
I
, using IPython notebook in%matplotlib
inline mode with the plot commandplt.plot(I,'o')
.The resulting output is:
<matplotlib.figure.Figure at 0x119e6ead0> Out[159]: [<matplotlib.lines.Line2D at 0x11ac57090>, <matplotlib.lines.Line2D at 0x11ac57310>, <matplotlib.lines.Line2D at 0x11ac57510>, <matplotlib.lines.Line2D at 0x11ac57690>, <matplotlib.lines.Line2D at 0x11ac57810>, <matplotlib.lines.Line2D at 0x11ac57990>, <matplotlib.lines.Line2D at 0x11ac57b10>, .... .... ]
Then my plot shows up below these lines of output.
Is there a way to just show the plot and hide the
<matplotlib.lines.Line2D at ...>
from the output? -
will over 9 yearsThey could also be stored to a variable too, which would not print to the workbook i think.
