I have a vector I need to plot that contains numerics gathered from a data acquisition board collecting at 1 hz (1 point / sec).
any time signal is lost, a placeholder "-1" value is used in that cell and I need to plot this vector but not have it plot the "-1"s
is the plot function capable of such a task? or do I have to remove all the "-1"s first?

You can set those values to NaN
x(x == -1) = NaN;
plot(x)
They will show up as gaps in your plot.

You can just plot x for x~= -1 or did you mean that the character array "-1" is entered? Not sure what you mean by the " ".
x = randi([-1 4],20,1);
plot(x(x~= -1))
