Overlaying a Function Graph on a Statistical Graph
You can overlay an existing statistical graph with any type of function graph.
Example:
Input the two sets of data shown below, and plot the data on a scatter plot. Next,
overlay the scatter plot with the graph of
y
= 2 · ln(
x
).
list1 = 0.5, 1.2, 2.4, 4.0, 5.2
list2 = –2.1, 0.3, 1.5, 2.0, 2.4
