How to draw indicator partially

[Marco Montemari]

Hi Folks,

I am adapting an indicator but i am not able to do the following task.

The indicator must be drawn until (rates_total-X) ....what I get is ok but at rates_total-X a vertical line is drown and the folliwing values are 0.
How can I draw the line until (rates_total-X) skipping drawing the following values?
Thanks
