Plot width settings in ipython notebook

Question

I've got the following plots:

sound signals

It would look nicer if they have the same width. Do you have any idea how to do it in ipython notebook when I am using %matplotlib inline?

UPDATE:

To generate both figures I am using the following functions:

import numpy as np
import matplotlib.pyplot as plt

def show_plots2d(title, plots, points, xlabel = '', ylabel = ''):
    """
    Shows 2D plot.

    Arguments:
        title : string
            Title of the plot.
        plots : array_like of pairs like array_like and array_like
            List of pairs,
            where first element is x axis and the second is the y axis.
        points : array_like of pairs like integer and integer
            List of pairs,
            where first element is x coordinate
            and the second is the y coordinate.
        xlabel : string
            Label of x axis
        ylabel : string
            Label of y axis
    """
    xv, yv = zip(*plots)
    y_exclNone = [y[y != np.array(None)] for y in yv]
    y_mins, y_maxs = zip(*
        [(float(min(y)), float(max(y))) for y in y_exclNone]
    )
    y_min = min(y_mins)
    y_max = max(y_maxs)
    y_amp = y_max - y_min
    plt.figure().suptitle(title)
    plt.axis(
        [xv[0][0], xv[0][-1], y_min - 0.3 * y_amp, y_max + 0.3 * y_amp]
    )
    plt.xlabel(xlabel)
    plt.ylabel(ylabel)
    for x, y in plots:
        plt.plot(x, y)
    for x, y in points:
        plt.plot(x, y, 'bo')
    plt.show()

If you use %pylab inline you can (on a new line) insert the following command:

%pylab inline
pylab.rcParams['figure.figsize'] = (10, 6)

This will set all figures in your document (unless otherwise specified) to be of the size (10, 6), where the first entry is the width and the second is the height.

See this SO post for more details. https://stackoverflow.com/a/17231361/1419668

simply figsize(10, 6) does the job and times easier to remember.

This is way I did it:

%matplotlib inline
import matplotlib.pyplot as plt
plt.rcParams["figure.figsize"] = (12, 9) # (w, h)

You can define your own sizes.

plt.rcParams["figure.figsize"] =(12,9) also this works

If you're not in an ipython notebook (like the OP), you can also just declare the size when you declare the figure:

width = 12
height = 12
plt.figure(figsize=(width, height))

Do you have any idea in which units this is measured?

hobs Over a year ago

Units are inches, but YMMV (your display's DPI may not match matplotlib's assumptions). Also, this won't work in the OP's environment, an iPython Notebook!

@hobs which version of iPython notebook are you running? it is working for me in Jupyter.

Ott Toomet Over a year ago

Works for me in emacs/ein 20161228.741

@hobs this works for me in ipython. My site's ipython is slightly hacked, but I would be very surprised if it didn't work for generic ipython as well.
