Bokeh如何拥有覆盖直方图

from bokeh.plotting import figure, show

# 创建一个图表对象
p = figure(title="Overlay Histogram", x_axis_label="Value", y_axis_label="Count")

# 数据集1
data1 = [1, 2, 3, 4, 5]
hist1, edges1 = np.histogram(data1, bins=5)
p.quad(top=hist1, bottom=0, left=edges1[:-1], right=edges1[1:], fill_color="blue", line_color="black", alpha=0.5, legend_label="Data 1")

# 数据集2
data2 = [2, 3, 4, 5, 6]
hist2, edges2 = np.histogram(data2, bins=5)
p.quad(top=hist2, bottom=0, left=edges2[:-1], right=edges2[1:], fill_color="red", line_color="black", alpha=0.5, legend_label="Data 2")

# 显示图表
show(p)
