Is there a easyer/faster way to draw 64 point from an array
Is there a faster or easyer way to draw a 64 point curve ?
This is working ok but I think there must be a better way.
This was one of my trials ( )

maybe something along this:
not tested... just guessed
- Code: Select all
v.drawCurve(p_ch2, @c.map.with_index { |x,i| [i*5+10, x] })
not tested... just guessed

Myco,
It works
I do my best to know more about the ruby posibilities but you are very fast in answering....
When do I receive your invoice?

x seems to be a fixed list of values. If that's right, you can also create that list elsewhere (for example in init-method) and for drawing just call
v.drawCurve(p_ch2, @x_list.zip(@c))
where @x_list is your array of x-positions. This is faster than mapping, because you don't need to calculate the x-values on each redraw.
