DPlot

Dear Administrator,

Can you propose a method how to determine easily the meeting of two lines in ternary phase diagram, i.e. I have two fitting curve, and I want to know at what x;y position they meet.

I know I can calculate it on a paper, but maybe there is a function already in DPlot.
Thanks,

Dear administrator,

I'm in ternary phase diagram. I request curve fit for certain points, and I obtain the equation of the line.
By the equation of the linear fit curve (equation) I'd like to present the Correlation coefficient (R2).
I did not find how to do it.
Can you help?
Thank you,

Thank you,
It works what you proposed, and anyway what is important for me is the equation, which is not affected by this change.

Dear users, administrators,

I'm a new user, maybe the problem is not in the program but in the user...

I started to work with ternary phase diagram.
I enter series of points into the ternary diagram and I want to present the points together with their linear fit curve (equation) on the same graph ...
