X-Y-Z Scatterplots in Excel, or similar program

Hello all, I went through a series of tests with MSI Afterburner trying to determine a ratio, or some kind of pattern to core clock and memory clock for optimal performance on the Nvidia GTX 680M at its stock voltage. I gathered all of my data, but can't find a way in excel to have the core and memory speeds as X and Y axes, then the P Score from 3DMark11 as a third item on the Z axis. Here's my data if anyone's interested:

 

Well, you could do a dual Y axis plot if worse comes to pass, it will still allow you to show the data on the same plot. From what i can tell Excel 2010 and prior can't do 3D scatterplots I could check in office 15 though, but first, dinner...

EDIT:

Been a while since i used MATLAB, here's what i pulled off on short notice:



Here's the code i used by the way:

Code:

core_clock = [719 719 719 719 719 719 719 719 749 749 749 784 784 784 819 819 819 854 854 854];
memory_clock = [900 950 1000 1050 1100 1150 1200 1250 900 950 1000 900 950 1000 900 950 1000 900 950 1000];
p_score = [6100 6135 6157 6180 6197 6223 6251 6239 6267 6327 6347 6491 6529 6588 6720 6772 6803 6919 6976 7008];

scatter3(core_clock, memory_clock, p_score, 100, 'black', 'filled')
title('GTX680m Overclocking Results')
xlabel('Core Clock')
ylabel('Memory Clock')
zlabel('P Score 3D Mark 11')
axis([700 900 850 1100 6000 7100])

 

Thank you very much. I don't have MATLAB, nor do I know how to use it, although I will be learning in a couple of weeks. That was pretty much exactly what I was looking for though, thank you very much.
