Which Scilab version do you use?
I have tried your code on Scilab-5.5.2 and it gives good result.

The y axis of your plot ranges from 1 to 1, so if a value is slightly less than 1 (due to rounding errors) the bar dispears

You can fix the problem changing the y axis limits
ax=gca();
ax.data_bounds(1,2)=0;
