散点图重叠轴

Question

由于某种原因，当我在散点图中使用zorder时，点的边缘与轴重叠。我尝试了[here]（matplotlib axis tick labels covered by scatterplot (using spines)）中的一些解决方案，但它们对我不起作用。有办法防止这种情况发生吗？

我知道我也可以在边界添加一个ax.axvline()，但这对于许多地块来说是个烦人的解决方法。

xval = np.array([0,0,0,3,3,3,0,2,3,0])
yval = np.array([0,2,3,5,1,0,1,0,4,5])
zval = yval**2-4

fig = plt.figure(figsize=(6,6))

ax = plt.subplot(111)

ax.scatter(xval,yval,cmap=plt.cm.rainbow,c=zval,s=550,zorder=20)

ax.set_ylim(0,5)
ax.set_xlim(0,3)


#These don't work
ax.tick_params(labelcolor='k', zorder=100)
ax.tick_params(direction='out', length=4, color='k', zorder=100)

#This will work but I don't want to have to do this for the plot edges every time
ax.axvline(0,c='k',zorder=100)


plt.show()

Answer 1

对我来说，您链接的解决方案有效；也就是说，将散点图的z阶设置为负数。例如

xval = np.array([0,0,0,3,3,3,0,2,3,0])
yval = np.array([0,2,3,5,1,0,1,0,4,5])
zval = yval**2-4

fig = plt.figure(figsize=(6,6))

ax = plt.subplot(111)

ax.scatter(xval,yval,cmap=plt.cm.rainbow,c=zval,s=550,zorder=-1)

ax.set_ylim(0,5)
ax.set_xlim(0,3)

plt.show()

您的圆的大小足够大，以至于超出了轴范围。因此，我们只需更改import numpy as np import matplotlib.pyplot as plt xval = np.array([0,0,0,3,3,3,0,2,3,0]) yval = np.array([0,2,3,5,1,0,1,0,4,5]) zval = yval**2-4 fig = plt.figure(figsize=(6,6)) ax = plt.subplot(111) ax.scatter(xval,yval,cmap=plt.cm.rainbow,c=zval,s=550,zorder=20) ax.set_ylim(-1,6) ax.set_xlim(-1,4) #These don't work ax.tick_params(labelcolor='k', zorder=100) ax.tick_params(direction='out', length=4, color='k', zorder=100) #This will work but I don't want to have to do this for the plot edges every time ax.axvline(0,c='k',zorder=100) plt.show() 和ylim

已更改

xlim

到

ax.set_ylim(0,5)
ax.set_xlim(0,3)

此外，zorder在将点推到边缘时不起作用。

Answer 3

您可以使用以下带有zorder的大量代码来修复重叠。这将同时在x轴和y轴上起作用。

for k,spine in ax.spines.items():
    spine.set_zorder(1000)
