How not to plot blank/zero points? [message #67544]

I have an array (matrix, about 13 columns) of strings consisting of
numbers and blanks*. When I plot the data in each column, the blanks
get plotted as zeroes, so if I just plot points, things are OK (as
long as I start my plot range above 0), but if I want to connect the
points with lines then there are lines going to and from these blank
points.

How do I make IDL not plot these blank points (or points equal to 0)?
The only way I've found is by plotting in log (so the points don't
even show up) but for various reasons I'd rather not use log.

*If I were to do this as a floating point array, the blanks all become
0.000, and that doesn't help.
