single point in (0,0) using plot multy x-y

[aaa1982]

hi

I want to display two waveform(in  points )in  x-y coordinate(the x-y coordinate must be shown),

my method is  using  plot multy-xy.vi

1.initial a array(length:20   all number is 0)

2.using shift register and replace the index element of the array

3.using   plot multy x-y to dynamic display the array 

but when the plot multy-xy was used,  the (0,0) is always the first point.

the detail is in the attached file

your problem lies in the small points drawn on the screen

I changed your program so that I could read it and added a Quotient and remainder function so that after 20 points the loop would continue.

Just wait for 20 points and see what happens after that
