Question #213372 on Graphite changed:

Stefan Wehner posted a new comment:
I think the keepLastValue function a drawback if used to interpolate null values.
While it does fix small gaps, if a metric doesn't have data after a certain time, keepLastValue will maintain the last value throughout the whole graph, which might not make that much sense.
I think a more specific interpolation function which could take an average value between the previous and next value and NULL if any of these are NULL would make some sense.
