How can you graph a function with 3 variables?

Examle:

thrust = Function(fuelTypeA, fuelTypeB, AirRatio)

I'd like to graph all 3 variables in a 3d chart then have the countour be thrust.

But since you can only use x, y, z values for points I'm not sure if this is possible.

Any ideas or suggestions would be greatly appreciated.

Thanks

Hi ja,

I'm not sure about what do you exactly mean here. You could use X, Y and Z values to populate a contour series as described here. If this doesn't help please give us more detailed information about what you are trying to do.

Thanks in advance.

So let's say the Z axis is fuel type "A".
And the X axis is fuel type "B"
Which axis would be the "Air Mixture"?

The Y Axis would be thrust.

So even though theirs 3 variables the "Thrust" which is the most important is really the 4th value.

So 3 Variables go into the function to predict thrust and I'd like to graph all 4 numbers if possible.

Hi ja,

Do you have an image example of this kind of charts?

Thanks in advance.

No,

I think due to it's complexity it's always a report.

Probably I should stick to that or lose a variable.

Because I think I'd have to add more axis or another dimension somehow
and just the thought of that hurts my brain.

Thanks,

Hi ja,

Yes, I think that would be a 4 dimension chart. You could make 3 three dimensional charts: one with A, B and T, one with A, C and T and last one with B,C and T. Maybe using this the person who looks at the chart can get an idea of the whole picture. Or maybe a Ternary series could also help here.
