[Scilab-users] Plot error

[Einstom Engay]

Hi,

I have previously used the function plot and it worked well. But, every time i used it now it outputs the error 21. 

-->x = [-5:5]
 x  =
 
  - 5.  - 4.  - 3.  - 2.  - 1.    0.    1.    2.    3.    4.    5.  
 
-->plot(x)
 !--error 21 
Invalid index.

at line     327 of function _mainPlot called by :  
at line      28 of function plot called by :  
plot(x)
 

I am a windows 7 user. Please help me fix this.
Thanks a lot,

Tom
