嗨，我在python中使用fill_between命令，但是看起来fill_between总是在线图下面。
看这个例子，alpha=1，所以它不是不可见的。当所有的线都在两个位置之间的填充区时，不应该看到它们。但我仍然看到他们。
伊普顿——派拉布
plot([0,1],[1,1],'r')
plot([0,1],[2,2],'g')
plot([0,1],[0.5,0.5],'b')
plot([0,1],[3,3],'k')
fill_between([0,0.25],[0,3.5],facecolor='LightGreen')
fill_between([0.3,0.45],[0,3.5],facecolor='Salmon')
fill_between([0.5,0.7],[0,3.5],facecolor='LightBlue')
fill_between([0.75,0.95],[0,3.5],facecolor='LightYellow')
当我使用alpha=0.5时，我仍然得到一些不正确的结果，正确的行为是，当每一行与中间的fill_位于同一位置时，每一行都会改变颜色，但是你看到行的颜色不会改变……
plot([0,1],[1,1],'r')
plot([0,1],[2,2],'g')
plot([0,1],[0.5,0.5],'b')
plot([0,1],[3,3],'k')
fill_between([0,0.25],[0,3.5],facecolor='LightGreen',alpha=0.5)
fill_between([0.3,0.45],[0,3.5],facecolor='Salmon',alpha=0.5)
fill_between([0.5,0.7],[0,3.5],facecolor='LightBlue',alpha=0.5)
fill_between([0.75,0.95],[0,3.5],facecolor='LightYellow',alpha=0.5)
最佳答案
您可以使用zorderkwarg修复此问题：
plot([0,1],[1,1],'r',zorder=1)
plot([0,1],[2,2],'g',zorder=1)
plot([0,1],[0.5,0.5],'b',zorder=1)
plot([0,1],[3,3],'k',zorder=1)
fill_between([0,0.25],[0,3.5],facecolor='LightGreen',zorder=2)
fill_between([0.3,0.45],[0,3.5],facecolor='Salmon',zorder=2)
fill_between([0.5,0.7],[0,3.5],facecolor='LightBlue',zorder=2)
fill_between([0.75,0.95],[0,3.5],facecolor='LightYellow',zorder=2)
关于python - fill_between始终位于绘图线下方，我们在Stack Overflow上找到一个类似的问题：https://stackoverflow.com/questions/28542933/
