thanks. you did not answer the first two questions. the reason I asked the 1st question is I found the colors in positive and negative are slightly different. I hope it can be set colors for both side. from your answer, you seem say you dont have way to set (is it right?). in the last email, I tried to say it seem not logical that dose not allow users to show bars for overlap region (I am sorry for giving negative opinion). I can not find reason why USCS browser gave this restriction. it seems OK if the restriction is removed. you suggested using two tracks or color. I am sorry it is not suitable for my case. I really enjoy UCSC genome browser! thanks YU

This means that your positive and negative strand data cannot be displayed together if they have overlapping regions. Unfortunately, given your current needs, I think it would be best that you use two separate custom tracks to represent your data. You will lose the overlap, but will be able to customize the color and display of each track to your liking. We are working on a means to overlay separate data sets, but we currently have no time line as to when this feature will be added.
