Duval Triangle

My implementation of the Duval's Triangle.

Provides a real-time diagnostic of a Dissolve Gas Analysis (DGA).

The UI is quite intuitive. Use only the mouse. The cursor acts as a toggle button. The first click activates the abacus, and lets you finely adjust the three parameters (C2H2, CH4 and C2H4). When you are done, you can freeze your settings by clicking a second time within the triangle area.

Of course, you can restart with another click and toggle again in active mode.
