Did you try the PREV variable (or rather function) ? You could say: if UN then PREV else normal value.
I don't know if a value followed by two consecutive NaN's will be changed to three times the same value, but you can give it a go yourself to try. A nice option may be to draw two lines. One in (for instance) green with the regular values and one in red which shows only the NaN's changed in PREV values.

When creating the graph, I know I can do this: CDEF:value=value,UN,0,value,IF to set the value to 0 if it is NaN. Is it possible that whenever I find a NaN, I use the value of the previous non-NaN PDP? Basically can I store value in a variable and use it? Or some other way? Please help.
