Create a 3D surface plot

You can create a 3D surface plot that represents the relationship between three variables.

For example, this 3D surface plot shows how reheat time (y) and temperature (x) affect the quality (contours) of a frozen entree.

To create a 3D surface plot, you must use a worksheet that contains three columns of measurement data: one response variable (Z) and two predictor variables (X and Y).

Example worksheet

C1 C2 C3
Temp Time Quality
350 24 0.1
350 26 0.2
350 28 1.1

  1. Choose Graph > 3D Surface Plot.
  2. Choose Surface, then click OK.
  3. Under Z variable, enter the response variable. In the example, Quality is the Z variable.
  4. Under Y variable, enter the predictor variable to appear on the Y-axis. In the example, Temp is the Y variable.
  5. Under X variable, enter the predictor variable to appear on the X-axis. In the example, Time is the X variable.
  6. Click OK.
