Function Graphing Update Part II
I’ve been very quiet over the last few months, and for good reason. Just finished a gig involving two pretty complex learning applications for physical science. I worked on one as a primary developer, and the function graphing engine I authored was used in another. This is the first of a couple posts summarizing the work before returning to development of the Freehand Drawing Library.
The prior update on the function graphing engine was summarized in this post. This particular learning application involves chemical reactions and equilibrium. A simulation is started in one tab, as shown below.
Depending on the simulation length, a substantial number of molecules may interact in a single time step. Clicking on the Graph tab shows a real-time line plot of the state of various reactions.
The x-axis is time steps and the programmer plots the most recent N steps.
A new addition to the graphing engine is the ability to adjust x- and y-axis bounds and tic marks independently. This provides highly customizable zoom capability.
The graph may be panned by dragging, and panning is setup in XML to be restricted to the first quadrant.
This was a very interesting project both because I enjoyed working with the other application developer and to see a cool use of the function graphing engine.
