Graphics, Figures & Tables ⇒ Plotting an array of numbers using Tikz

[jhapk]

I have an array of numbers, ZX, as follows of size N=12.

• -1.0000000000000000
  -0.94489927222288217
  -0.81927932164400663
  -0.63287615303186073
  -0.39953094096534891
  -0.13655293285492756
  0.13655293285492756
  0.39953094096534891
  0.63287615303186073
  0.81927932164400663
  0.94489927222288217
  1.0000000000000000

Depending on N, these values of ZX change. ZX always remain in the range (-1,1). I want to make a square with corners at (-1,-1) to (1,1) and have lines inserted based on the values of ZX as shown in the following figure (in this case N=5):

I don't know how can I use the values of an array to plot lines in Tikzpicture. Can someone help me here?
Thanks

Hi,

such a drawing is not very hard. I think automating could be a challenge, or reading from a file, but for a certain N and a list of ZX values in the code it should be easy.

How far did you come? Do you have some code for a start? Where is the problem - loop, thick point, lines, ... ? We gladly help but it's easier if you would provide a starting point.
