Question:
How do I change the name of a variable in the contour legend box? See Figure 1.

Figure 1: The contour legend for the “temperature” variable doesn’t match the other legend. It is too long and doesn’t give units. It’s time to rename it.
Solution:
Renaming a contour variable requires altering the variable name in the Data Set Information dialog box:
1) In Tecplot 360, go to Data>Data Set Info… (see Figure 2).
2) Double-click the name of the variable displayed in the contour legend and replace it with the desired name.

Figure 2: Double-click and change the variable to a more suitable name.
VoilĂ , the contour legend dialog box changed accordingly in Figure 3:

Figure 3: Both contour variable styles now match.
