Great to have the Mandelbrot set available on the DM42. Thank you!
I'd suggest one minor change related to rendering. Personally I like the escape time based coloring. This requires only a minor change in the program.

Here is the modified program:

Sorry but, donloaded your program and I get the same result (no escape time based color) as initial version.
Did I miss something ?

Fantastic ! As this calc. I have added a benchmark prog to add on the grap iterations' number + time to complete the figure
Not time now but I will come back with pictures + programs

Same here. I get no difference.

I too do not get the nicer escape value image.

What are the parameters people are using to get the pretty / properly scaled M-set image?

Thank you

Added my "bench" programs to visualise iterations' number + running time. Also modified the Mandel program to interact with the second one.
You can see impact of iterations' number compared to time spent to draw the set

Ooops, I think I have mixed some pictures as some runs were made on usb power supply and some not (3x slower).

Hello Stéphane,
You may add your raw files as zip files, like in
