Plotting from function per for-loop iteration

I need to produce calculations and plots for a series of parameters. I have read that producing a new plot per for-loop iteration is not advised, but that is what I need. For example, I have the following function and code:
Function:
function test_function(input_test)
x = input_test.x;
y = input_test.y;
x+y
figure(1)
scatter(x,y)
figure(2)
scatter(x+y,y)
end
Code:
a = [1,2,3];
b = [1,2,4];
for i=1:3
for j = 1:3
input_test.x=a(i)
input_test.y=b(j)
test_function(input_test)
end
end
I want to call the function and output the calculation and plots for each iteration of the for-loop (ie: 9 calculations of x+y & 18 different plots). Right now this code can produce the 9 calculations of x+y but I am only getting the 2 plots of the last iteration at the bottom of the output window.
Any suggestions or other methods on how to produce a series of individual calculations and plots?

If you want new figure windows for each plot, don't specify a number for them:
figure
scatter(x,y)
figure
scatter(x+y,y)
