[英]In Matplotlib, How to avoid axvspan overlap?
I noticed that two adjacent areas overlap, so in the middle appear an annoying line. 我注意到两个相邻区域重叠,所以在中间出现一条恼人的线。 I tried "capstyle = 'butt'" which I used to avoid overlap between lines, but here it doesn't do the job. 我试过“capstyle ='butt'”,我曾经避免使用线条之间的重叠,但是这里没有做到这一点。
here's a minimal example: 这是一个最小的例子:
import matplotlib.pylab as plt
ax = plt.subplot(111)
ax.axvspan(0, 0.5, color = 'red', alpha = 0.13, capstyle = 'butt')
ax.axvspan(0.5, 1, color = 'blue', alpha = 0.13, capstyle = 'butt')
plt.show()
The problem you have is not due to line caps, since axvspan draws a polygon. 你遇到的问题不是由于线帽,因为axvspan绘制了一个多边形。 The problem is that this polygon, by default, has a border with a given linewidth (one pixel, I suppose). 问题是这个多边形默认情况下有一个给定线宽的边框(我想是一个像素)。
So, to get just the areas without that "border", set the linewidth ( lw
) to zero: 因此,要获得没有“边界”的区域,请将线宽( lw
)设置为零:
import matplotlib.pylab as plt
ax = plt.subplot(111)
ax.axvspan(0, 0.5, color = 'red', alpha = 0.13, lw=0)
ax.axvspan(0.5, 1, color = 'blue', alpha = 0.13, lw=0)
plt.show()
Instead of color
, use facecolor
inside axvspan
. 相反的color
,使用facecolor
内axvspan
。 The solution by @heltonbiker works great, it gets rid of the width of the border. @heltonbiker的解决方案效果很好,它摆脱了边框的宽度。 But, at least in the matplotlib version I'm using, 2.0.0, using just facecolor
doesn't draw the border. 但是,至少在我使用的matplotlib版本2.0.0中,仅使用facecolor
不会绘制边框。
import matplotlib.pylab as plt
fig,ax = plt.subplots()
ax.axvspan(0, 0.5, facecolor = 'red', alpha = 0.13)
ax.axvspan(0.5, 1, facecolor = 'blue', alpha = 0.13)
plt.show()
Using only facecolor
will no draw the border: 仅使用facecolor
将不会绘制边框:
Using color
will fill the rectangle and will draw a border: 使用color
将填充矩形并绘制边框:
