How can I plotting a big vector using low resolution?
===

I have a big array, have 640000 elements type double.
I need to plot values, but the array's length is enormous and it consumes processor resources.

The resolution of my screen is only 600x600.

How can I to shrink my big array for plot it with only 400 possible values(200 dots for borders).

I was trying to use Java, but I have no idea for beging...

Thanks
