Python Matplotlib Histogram Color
提问by user58925
I hope you are well.
我希望你一切都好。
I am plotting a histogram using Matplotlib. I would like the color of the histogram to be "sky blue". But the data overlaps, and produces a histogram which is nearly black in color.
我正在使用 Matplotlib 绘制直方图。我希望直方图的颜色为“天蓝色”。但数据重叠，并产生一个颜色接近黑色的直方图。
Thanks for helping
谢谢你的帮助
plt.hist(data, color = "skyblue")
Below is how the histogram looks. As you can see, though I've specified the color as "Skyblue, the histogram on the right is nearly black 
下面是直方图的外观。如您所见，虽然我已将颜色指定为“天蓝色”，但右侧的直方图几乎为黑色
回答by ImportanceOfBeingErnest
The reason for the histogram to look black is that the bars' surrounding lines (which are black) take most of the space.
直方图看起来是黑色的原因是条形周围的线条（黑色）占据了大部分空间。
Options would be to get rid of the edges by setting the linewidth to zero:
选项是通过将线宽设置为零来消除边缘：
plt.hist(data, color = "skyblue", lw=0)
and/or to set the edgecolor to the same color as the bars itself
和/或将边缘颜色设置为与条形本身相同的颜色
plt.hist(data, color = "skyblue", ec="skyblue")
