Hello everyone,
I've tried multiple ways of calculating the area, but I always get a value that's strange. I'll explain.
My curve is attatched.https://my.originlab.com/ftp/forum_and_kbase/Images/ternary_diagram_calculate_area.opju
When I use the Analysis>Mathematics>Integrate, I aways get a negative value that makes no sense to the ocupation of the area viewed in the graph. I wanted to get a % value of the area above the curve, but if I get the % value of the area below, that works too, because it's complementary.
I thank you all in advance! |

Hello josecqneto,
Please see this page: https://www.originlab.com/doc/Quick-Help/Area-Calculation-in-2D-Ternary
Ternary plots don't use Cartesian coordinates so you will have to multiply the value by sqrt(3)/2.
If you want to area above the curve, you can highlight columns X and Z instead.
Best,
Chao |
