是否有任何方法可以将叠加层添加到bokeh图上，从而基于x轴数据点突出显示某些区域.见下图

问题描述

我正在x轴和y轴上绘制一些数据，这些数据给出了峰值.我想用多种颜色突出显示峰的某些区域.

I am plotting some data on x-axis and y-axis which gives peaks. I want to highlight certain areas of the peaks in multiple colors.

我能够获得该图，但是不知道如何在该图上添加叠加层

I was able to get the plot but have no clue on how to add overlays to the plot

推荐答案

您可以为此使用BoxAnnotation.优点之一是，它始终会覆盖图的整个高度.

You could use BoxAnnotation for this. One advantage is that it always span entire height of the plot.

from bokeh.plotting import figure, show
from bokeh.models import BoxAnnotation

p = figure(plot_width=400, plot_height=400)

p.line([1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12], [1, 3, 2, 8, 2, 1, 2, 3, 1, 9, 1, 2], line_width=2)
b1 = BoxAnnotation(left=3, right = 5, fill_color = 'red', fill_alpha = 0.5)
b2 = BoxAnnotation(left=9, right = 11, fill_color = 'green', fill_alpha = 0.5)
p.add_layout(b1)
p.add_layout(b2)
p.text([4, 10], [0, 0], ['area1', 'area2'], y_offset = -10, x_offset = -20)
show(p)
