how to get the maximum x, y value from main effects plot graph

Hi,

I have develop a main effects plot using y and x(9x3 matrix array). I have got 3 main effects plot for x1,x2 and x3.

maineffectsplot(y,x)

The question is how to get the maximum value from the main effect plot to be display in command window?

Hi, could you clarify here? What is it that you want? Do you have the data as matrices or do you want to extract data from the plot? What is the size of y, the same as x? Do you want the max of all main effects or the max of every main effect separately? Do you want to know the maximum value or do you just want to know how to display a value?
