1)I need a arrowhead attached to the 1D XY line to indicate the time advancing direction. But this can only be realized in 2D streamtraces cases.

2)Another problem is related to contour, I want the positive value on the contour to be showed in solid line and negative value to be showed in dashedline, this function is also unavailable in tecplot, it just show all positive and negative value in the same type of line.

Anyone know how to solve these two problems?

Or are there some other softwares to realize these two functions?

Thanks!

I have solved the second problem: contour details->lines check dashed negative lines.

How to solve the first one?

probably I don't understand because I think you can simply make a draw using the tools
