我想在matplotlib的broken_barh中使用阴影。我想要的是为不同的颜色在剧情中有不同的孵化模式。我试图添加为字典,但没有成功,任何人都知道什么是正确的方式? 这是来自matplotlib网站的示例代码。如何孵化matplotlib python上的broken_barh?

“”“ 做一个‘破’水平条形图,即一有间隙 ‘’”

import matplotlib.pyplot as plt 

fig, ax = plt.subplots() 
ax.broken_barh([(110, 30), (150, 10)], (10, 9), facecolors='blue', hatch='o') 
ax.broken_barh([(10, 50), (100, 20), (130, 10)], (20, 9), 
       facecolors=('red', 'yellow', 'green'), hatch='//') 
ax.set_ylim(5, 35) 
ax.set_xlim(0, 200) 
ax.set_xlabel('seconds since start') 
ax.set_yticks([15, 25]) 
ax.set_yticklabels(['Bill', 'Jim']) 
ax.grid(True) 
ax.annotate('race interrupted', (61, 25), 
      xytext=(0.8, 0.9), textcoords='axes fraction', 
      arrowprops=dict(facecolor='black', shrink=0.05), 
      fontsize=16, 
      horizontalalignment='right', verticalalignment='top') 

plt.show() 

我想有不同的孵化不同的颜色,但它是不可能的:
I want to have different hatching for different color, but it is not possible

我希望如果有人能给我一个提示如何做到这一点?

broken_barh不允许设置不同的舱口盖。但是因为一个破损的酒吧只是许多单个酒吧,您可以绘制不同舱位的单个酒吧。

import matplotlib.pyplot as plt 

def brokenhatchbar(xs, y, ax=None, **kw): 
    if not ax: ax=plt.gca() 
    hatches = kw.pop("hatch", [None]*len(xs)) 
    facecolors = kw.pop("facecolors", [None]*len(xs)) 
    edgecolors = kw.pop("edgecolors", [None]*len(xs)) 
    for i, x in enumerate(xs): 
     ax.barh(bottom=y[0], width=x[1], height=y[1], left=x[0], 
       facecolor=facecolors[i], edgecolor=edgecolors[i], hatch=hatches[i]) 

fig, ax = plt.subplots() 
brokenhatchbar([(110, 30), (150, 10)], (10, 9), facecolors=['blue','blue'], hatch=['o','////']) 
brokenhatchbar([(10, 50), (100, 20), (130, 10)], (20, 9), 
       facecolors=('red', 'yellow', 'green'), hatch=('//', 'o', '+')) 
ax.set_ylim(5, 35) 
ax.set_xlim(0, 200) 
ax.set_xlabel('seconds since start') 

ax.grid(True) 

plt.show()
