Interactive Histograms not updating with sliders

I believe you have all the elements to implement those requirements. In the example above if plot A and plot B are interdependent on the slider choices, then you can simply modify your callbacks and/or plotting functions. For example:

def callback_A(attr,new,old):
    hist_data_A.A_lwr = new[0]
    hist_data_A.A_upr = new[1]
    hist_data_A.source = hist_data_A.filt_df()
    hist_data_B.source = hist_data_B.filt_df()
    Graphs1.children[0] = plot_data_A()
    Graphs1.children[1] = plot_data_B()

Just a side note, I recently learnt that it’s always better to only update the column data source data property instead of creating a new object. Refer to this post.
