如何在每个子图中设置轴限制 [英] How to set axes limits in each subplot

问题描述

我用这个代码创建了一个子图:

I created a subplot figure with this code:

f, axs =plt.subplots(2,3)

现在在一个循环中，我通过执行以下操作在每个子图上绘制一个图:

Now on a loop I make a plot on each subplot by doing:

for i in range(5):
 plt.gcf().get_axes()[i].plot(x,u)

是否有类似的代码来设置我正在访问的子图的轴限制?

Is there a similar code to set the axis limits of the subplot I'm accessing ?

推荐答案

是的，有，但让​​我们在处理代码时清理一下:

Yes, there is, but let's clean up that code while we're at it:

f, axs = plt.subplots(2, 3)

for i in range(5): #are you sure you don't mean 2x3=6?
    axs.flat[i].plot(x, u)
    axs.flat[i].set_xlim(xmin, xmax)
    axs.flat[i].set_ylim(ymin, ymax) 

使用 axs.flat 将您的 axs (2,3)轴数组转换为长度为6的轴的平面迭代.比plt.gcf().get_axes().

Using axs.flat transforms your axs (2,3) array of Axes into a flat iterable of Axes of length 6. Much easier to use than plt.gcf().get_axes().

如果仅使用 range 语句在轴上进行迭代，而从不使用索引 i ，则仅在 axs 上进行迭代./p>

If you only are using the range statement to iterate over the axes and never use the index i, just iterate over axs.

f, axs = plt.subplots(2, 3)

for ax in axs.flat: #this will iterate over all 6 axes
    ax.plot(x, u)
    ax.set_xlim(xmin, xmax)
    ax.set_ylim(ymin, ymax)
