用fig.show（）内联一个IPython Notebook图形？ [英] Plot an IPython Notebook figure inline with fig.show()?

问题描述

我正在调用IPython Notebook的内联模式;

I'm calling the inline mode for IPython Notebook using;

%pylab inline

以下代码会立即在单元格中绘制一个数字;

And the following code plots a figure immediately at the cell;

fig = plt.figure()
axes = fig.add_axes([0, 0, 1, 1])

但是我想在一个单元格中创建绘图/轴等，稍后使用may绘图;

However I would like to create the plot/axes etc. in one cell, and plot later using maybe;

fig.show()

如何获得更多控制权内联模式？如果我不使用％pylab inline，它会在一个我不想要的单独窗口中创建绘图（并且它通常会冻结窗口）。

How do I gain more control of the inline mode? If I don't use %pylab inline, it creates the plot in a seperate window which I don't want (and it usually freezes the window).

推荐答案

所以我想你是什么想要的是：

So I guess what you want is this:

from matplotlib.backends.backend_agg import FigureCanvasAgg as fc
fig = Figure()
canvas = fc(fig)
ax = fig.add_subplot(1, 1, 1)
ax.plot(arange(10))

要在另一个单元格中显示情节，只需使用：

To display the plot in another cell simply use:

fig
