Eliminating vertical lines where graph jumps

I am graphing several functions over the same domain, each of which equals zero over different subdomains. The display shows vertical lines where each function jumps from zero to the non-zero values. Is there any way to erase these vertical connections on the graphs? Is there an eraser tool?

You can insert a new element into your data that has a value NAN. Lines do not go through nan elements. I don't know how to do it after it's been plotted but you can do it before you plot.

If you want a display that looks something like

                +++++
 
          +++++++   ++++++

but you are using stairs() and so are currently getting something like

                +++++
                +   +
          +++++++   ++++++

then you would either need to change away from using stairs() or you would have to insert two nans and use redundant t values, such as

[1 7 7 7 11 11 11 16], [0 0 nan 1 1 nan 0 0]
