Bokeh interactive dashboard can not remove lines from plot
问题 I am working on my first python Bokeh interactive dashboard. Plot default shows lines for group=a and group=b. When check box[1], plot will add lines for group=a1 and group=b1. When uncheck [1], line a1, b1 are supposed to be removed from plot, but they still stay in the plot. Below is my sample data and sample code. It can directly run in your jupyter notebook. Can any one help me out? Thank you very much! import pandas as pd import numpy as np import matplotlib.pylab as plt from bokeh.io
