caret中color bar怎么设置?

已经分别做出了左半球和右半球。
左半球t值最高是18.9,右半球t值最高是6.5,但是左右半球的color bar颜色分段情况是相同的。我想将左半球和右半球放到一张图片里,需要同时放左半球和右半球的color bar吗?

 I think it is best to make sure there is only one colorbar or one color mapping, or it may induce confusions.
You can snapshot left/right hemisphere seperately, then combine the results, this is always my favorite way about using Caret.
