iPython Notebook中的绘图宽度设置 [英] Plot width settings in ipython notebook

问题描述

我有以下情节:

如果它们具有相同的宽度，它将看起来更好.您是否知道在使用%matplotlib inline时如何在ipython笔记本中执行此操作?

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?

更新:

要生成两个图形，我正在使用以下功能:

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()

def show_plot3d(title, x, y, z, xlabel = '', ylabel = '', zlabel = ''):
    """
    Shows 3D plot.

    Arguments:
        title : string
            Title of the plot.
        x : array_like
            List of x coordinates
        y : array_like
            List of y coordinates
        z : array_like
            List of z coordinates
        xlabel : string
            Label of x axis
        ylabel : string
            Label of y axis
        zlabel : string
            Label of z axis
    """
    plt.figure().suptitle(title)
    plt.pcolormesh(x, y, z)
    plt.axis([x[0], x[-1], y[0], y[-1]])
    plt.xlabel(xlabel)
    plt.ylabel(ylabel)
    plt.colorbar().set_label(zlabel)
    plt.show()

推荐答案

如果使用%pylab inline，则可以(在新行中)插入以下命令:

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

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

这会将您文档中的所有图形(除非另有说明)设置为(10, 6)大小，其中第一个输入项是宽度，第二个输入项是高度.

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.
