Why is set_xlim() not setting the x-limits in my figure?
提问by Dan
I'm plotting some data with matplotlib. I want the plot to focus on a specific range of x-values, so I'm using set_xlim().
我正在用 matplotlib 绘制一些数据。我希望绘图专注于特定范围的 x 值，因此我使用 set_xlim()。
Roughly, my code looks like this:
粗略地说，我的代码如下所示：
fig=plt.figure()
ax=fig.add_subplot(111)
for ydata in ydatalist:
ax.plot(x_data,y_data[0],label=ydata[1])
ax.set_xlim(left=0.0,right=1000)
plt.savefig(filename)
When I look at the plot, the x range ends up being from 0 to 12000. This occurs whether set_xlim() occurs before or after plot(). Why is set_xlim() not working in this situation?
当我查看绘图时，x 范围最终从 0 到 12000。无论 set_xlim() 发生在 plot() 之前还是之后，都会发生这种情况。为什么 set_xlim() 在这种情况下不起作用？

Out of curiosity, what about switching in the old xminand xmax?
出于好奇，切换旧的xmin和xmax？
fig=plt.figure()
ax=fig.add_subplot(111)
ax.plot(x_data,y_data)
ax.set_xlim(xmin=0.0, xmax=1000)
plt.savefig(filename)

set_xlim()limits the data that is displayed on the plot.
set_xlim()限制图上显示的数据。
In order to change the bounds of the axis, use set_xbound().
要更改轴的边界，请使用set_xbound().
fig=plt.figure()
ax=fig.add_subplot(111)
ax.plot(x_data,y_data)
ax.set_xbound(lower=0.0, upper=1000)
plt.savefig(filename)

In my case the following solutions alone did not work:
就我而言，仅以下解决方案不起作用：
ax.set_xlim([0, 5.00])
ax.set_xbound(lower=0.0, upper=5.00)
However, setting the aspect using set_aspectworked, i.e:
但是，使用set_aspect工作设置方面，即：
ax.set_aspect('auto')
ax.set_xlim([0, 5.00])
ax.set_xbound(lower=0.0, upper=5.00)
