Hi, guys.

I have a matrix data consisting of x and y that can be used to plot different curves. But there are many intersection points between these curves, as shown in Fig. 1 and Fig. 2. Is it possible to remove these intersection ponints and make these curves varying approximately linearly with x?

Thanks.

Here is the data file.
