change x axis value

[erez10121012]

hi
i plot a graph in the dashboard, the x axis is series from 1 to 2001
i want to replace 1-2001 to 500-3000 (yes, the step is >1 because the array is 2000 steps)
the 500-3000 is only for the presentation in the dashboard if its help.

please see the picture and the code
