I want to enter a default list of (x,y) data for a scatter plot that the user can modify to create a different scatter plot.

I am not sure how exactly you want to do this but let me know whether this is what you want. User can change the array and unfocus from the input box to update.

@interact
def int_plot(str1 = input_box('[[1,2],[3,5],[4,2]]',type = str, label='array 1: ')):
    array1=eval(str1)
    scatter_plot(array1).show()

Yes, it's perfect. For the record, here's the code with a few bells and whistles added. @interact def int_plot(t1=text_control("Enter data as a list of pairs, and set window [a,b] by [c,d]."), str1 = input_box('[[1975,4123], [1980,3851], [1985,3461], [1990,2827], [1995,2515], [2000, 2092]]',type = str, label='data '), a = (1970), b = (2000), c = (2000), d = (4500) , xlabel= ('Year'), ylabel= ('Consumption')): array1=eval(str1) s=scatter_plot(array1, xmin=a, xmax = b, ymin=c, ymax=d, figsize=6, axes_labels=[str(xlabel),str(ylabel)]) show(s)
