画黑白带阴影线的柱状图（论文专用）_科学论文，柱状图，条纹hatch

Matplotlib代码：

        plt.text(a, b+0.05, '%.3f' % b, ha='center', va= 'bottom',fontsize=7)  
    plt.bar(location+width, time2,tick_label = name_list,width = width,label="1-2",alpha=0.8,color="w",edgecolor="k",hatch=".....")

    plt.show()

    read()

Matlab代码：

 在科技文献写作等过程中，我们往往需要粘贴柱状图或者条形图，图中以不同颜色对不同数据进行区分，然而当黑白打印时，色彩颜色往往难以区分，故而需要绘制带有黑白阴影的柱状图或者条形图。对比效果见图1。下面介绍具体实现方法，本程序主体由Ben Hinkle完成，我只是个中间搬运工。
