Ternplot

Plots ternary phase data on a ternary phase diagram.

Description

Acts like plot (responds to hold, etc), also includes ternlabel.m to label all three axes.

These 2 routines do exactly what I've been looking for hours now. Thanks !

Very useful and amazing work.

[joe salisbury]

thanks!

[Priam Pillai]

Excellent program. I used it for my lab reports works great.

[B N]

excellent,
thanks a lot

THANKS

[John Dow]

It's really cool!
it would be nice to have an option to draw more than one graph on the same figure. (hold on, hold off)

[Yash Mahendra]

Thank you so much!! It's a boon for chem engg students!

[Karel Verscheure]

Excellent work! Maybe someone can extend this to make advanced contourplots (liquidus surfaces in color etc.)?

Excellent work! Have you an Idea to get 3D ternary phase plot?

[Wolfgang Mozart]

I've been trying to use your solution for my data in excel file. I exported my data into matlab, but I got two errors:
??? Input argument "A" is undefined.

Error in ==> ternplot at 40
    C = 1 - (A+B);

??? Input argument "A" is undefined.

Error in ==> ternlabel at 18
r(1) = text(0.35*sin(deg2rad(30)), 0.5, A, 'rotation', 60, 'horizontalalignment', 'center');
How can I solve this problem?

Your work is excellent. Anyway there is a bug in ternplot.
Change line 33 in
function hpol = ternplot(A, B, C, varargin)
or, in alternative, change line 55 in
handles = q;

When I used ternplot some of my points are off the grid (outside the triangle) and I haven't been able to figure out the cause. Has this happened to anyone else? Can anyone help me fix the problem?

Thanks!

I'm pretty sure that vertexlabel.m is not working quite correctly. If the data input using ternplot is
% b
% / \
% / \
% c --- a

% this function plots
% c
% / \
% / \
% a --- b

% and the vertex labelling needs to be input as vertexlabel(C,A,B)

I need to make Piper trilinear diagrams using matlab. The ternary phase diagram is great, but it is only part of the Piper trilinear diagram (used to plot hydrogeochemical facies). Does anyone know how to create a Piper trilinear diagram in matlab?

[Dominique]

Thanks a lot, it works really well. I would like to plot tie-lines as well. Do you have any idea how I can do that?
