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.

v.drawCurve p_ch2,[
[   10   ,   @c[0 ]]   ,
[   15   ,   @c[1 ]]   ,
[   20   ,   @c[2 ]]   ,

[   320   ,   @c[62]]   ,
[   325   ,   @c[63]]   ,

This was one of my trials ( :lol:

)

Code: Select all

count   = 0

pointer = 0

v.drawCurve p_ch3,[
while count < 64
 [ @pointer +=10  , @c[count +=1]],
 end
]

maybe something along this:

Code: Select all

v.drawCurve(p_ch2, @c.map.with_index { |x,i| [i*5+10, x] })

not tested... just guessed

Myco,

It works :roll:

I do my best to know more about the ruby posibilities but you are very fast in answering....

When do I receive your invoice?

No invoice, but I accept PayPal donations :mrgreen:

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.
