Help needed urgent: Data blending while repect original shape 1

[jasminely]

Gurus please help!

For example, I have 0:00 to 0:17 data available, but missing out 0:18 to 0:56 and I have 0:57 data. I would want copy from yesterday's 0:18 to 0:56 to today and respect the values of today's 0:17 and 0:56. I need the copied data to be blended into today's data set and keep the original shape as much as possible and smooth out the whole copied data.
Big thanks!

Read yesterdays's data into a hash, with the 0:00 through 0:56 as the hash key.

Read today's data, and update the hash entries where you have data.

Write the hash back to disk. Use it as input to tomorrow's run. The data set will contain the most recent value for each hash bucket.

It sounds like that's what you want, anyway.
