For a real dirty LabVIEW Ninja trick...just set Y=NaN for the values you don't want displayed on the plot.

Should I resent being called a "dirty LabVIEW Ninja"?  [Look at my reply 5 earlier ...].

Substituting NaNs is a good way to hide selected points on waveform graphs. The original post asked about "deleting", not "hiding", though. 😄

The original data is however a 1D array and a dt scalar, so a waveform graph would have been the correct choice from the beginning. We can either set some values to NaN or get a subset and adjust t0 according. If there are billions of points and we only want to graph a few dozen, the subset is less demanding on the UI thread, of course. 😄
