dear professor paco and wolfgang,

is there an example of a recording data function that still remember the trace data even after _initialize(); ?

in the example attached (see zip file), i added a initialize button but the record data disappears when _initialize().

i need to figure out a way to record data for student to work on the recorded data.

thanks! i am working on adding new features onto this model by prof todd https://dl.dropboxusercontent.com/u/44365627/lookangEJSworkspace/export/ejs_KeplerSystem3rdLaw04.jar
