tecplot中的Color Map group 有何用

rolin212

最近比较糊涂，想请教tecplot中的Color Map group 有何用，怎么用？
看了帮助如下：
The Contour Details dialog in its condensed form.
• 1, 2, 3, 4, 5, 6, 7, 8 - Use the [1], [2], [3], [4], [5], [6], [7], and [8] buttons to specify attributes for a specific contour group. Each contour group has its own settings for the contour attributes established in the Contour Details dialog.
• Var - Assign a variable from your dataset to the active Contour Group (1, 2, 3, 4, 5, 6, 7, or 8).
还是不明白啊！
