How to prevent small lines from disappearing on zoom out?

I have a 2D curve that I am plotting as very small segments so I can change the color per segment. I have found that if I zoom out, the entire thing just disappears, perhaps due to some graphics optimization that considers each segment to be excessively small? Is there a way around this?

EDIT: For example:

for ii=0:1000
    plot([0 0],[ii*0.01 ii*0.01+0.01],'linewidth',3)
    hold on
end

Then,

axis([-100 100 -100 100])

At this point I have a blank plot.

Graphical representation would be useful.

See code above. Not worth posting a blank axis.

Possibly just being subsampled away when it displays on your screen in much fewer number of pixels?

Becuase you plot single points in every iteration and you haven‘t mentioned a marker for it

plot(...,'-ok','Linewidth',3)
    % remove axis(...)

It's not single points, it's very short lines. The reason I'm doing it (not shown in example above) is to color each segment a custom color. If I switch to points, they lay on top of each other annoyingly. I started there and went to this solution instead. Of course, this is failing for a different reason.

Look in the File Exchange for the colored line contribution based on surf or the one based on patch.
