For the 19000 points displayed it takes about 8 to 9 seconds in USB mode. It goes faster if you decrease the "n" interval, here 0.005. Without external power supply it takes 18 seconds.
One could also view the graph from smaller starting values (here I start at -4) to see the previous points of the Dr Fibonacci sequence.

That is quite nice. I looked in your program: Your run N from about -4 to 5, in steps of 5E-3, which is 1800 points. Looking at the crosses on my curve indicating the 100 points I used, you need maybe at most double what I had, so I would say for the same range, you can set it to 8x less, i.e. an increment of 0.005*8 = 0.04, for an 8 fold increase in speed without resolution issues on the graph.

Mine goes a lot slower, because of the interpreter. It is not the official programming, it is actually a mini sequencer, meant for small user programs on the soft keys only. I think the interpreter is the biggest time waster, because it searches very inefficiently for every command in a long text string, all the time, for every step. I do not plan to optimise it, or precompile it, or anything like that. It is an interim measure and not meant for speed and will stay until the real programming and programming space is created later by Martin.

In the mean time, until we can use the 43S programming also in my C43, it will remain slow and a sluggish temporary solution ;-)

Thanks very much guys for that great program idea ! :geek:
It makes full use of DM42 beautifull screen.

As an exercice, I was busy translating Jaymos WP43 version to my brand new DM42 when Pierre posted his working solution. :P

Learning a lot reading the program :ugeek:
Thanks again.
