问题描述
我有一个想要填充的区域，该区域位于虚线的现有绘图线(相同颜色)的边界上.
I have a region I'd like to hatch which borders on an existing plot line (of the same colour) that is dashed.
但是，当我使用 fill_between 时，要阴影的区域周围也绘制了边框.此边框似乎与创建影线的线条共享属性，因此我无法将边缘颜色设置为无"或将线型设置为--"，因为影线也受到类似影响.
However, when I use fill_between the region to be hatched has a border drawn around it also. This border seems share properties with the lines that create the hatching so I cannot set edgecolour to "none" or set linestyle as "--" as the hatching is similarly affected.
import matplotlib.pyploy as plt
plt.plot([0,1],[0,1],ls="--",c="b")
plt.fill_between([0,1],[0,1],color="none",hatch="X",edgecolor="b")
plt.show()
在这个例子中，我希望从 0,0 到 1,1 的对角线是虚线.
In this example I'd want the diagonal line from 0,0 to 1,1 to be dashed.
非常感谢.
推荐答案
> 2.0.1更新正如@CatherineHolloway所评论的那样，您需要使用 facecolor 而不是颜色:
>2.0.1 Update As commented by @CatherineHolloway you need to use facecolor instead of color now:
import matplotlib.pyplot as plt
plt.plot([0,1],[0,1],ls="--",c="b")
plt.fill_between([0,1],[0,1], facecolor="none", hatch="X", edgecolor="b", linewidth=0.0)
plt.show()
以前的答案
这似乎可以解决问题！
import matplotlib.pyplot as plt
plt.plot([0,1],[0,1],ls="--",c="b")
plt.fill_between([0,1],[0,1], color="none", hatch="X", edgecolor="b", linewidth=0.0)
plt.show()
