Hi , i'm tring to plot two functions x & y in the same graph in function of time , and i'm obliged to update values using ' set function ' . I tried this code but it doesn't work ?

"It doesn't work" is not a useful description of the occurring problems. Please show us the complete error message of explain the difference between your expectations and the results.
Because we do not now the values of plotGraph, time, x and y we cannot know, what this line exactly means. Please provide more details by editing the original question (hiding important information in comments or pseudo-answers is less useful).

What is the output of the following:
size(time)
size([x y])
get(plotGraph)

When you plot() with multiple columns, different lineseries() objects are produced for every column. You need to update both of the lineseries() objects with the appropriate individual column of data. You cannot set() a YData to a matrix of data, only a vector.
