I would like to plot a section of the time series but not include any of the points that are NaNs. That is, normally plot won't make any mark for the time when there is a NaN, but I want to completely skip these points because they just make the plot twice as long as necessary. Is there any way to do this other than creating a new array without those points?

plot, data[where(finite(data))]
