OriginPro 2022 (64-bit)
9.9.0.220 (Academic)
Win10 64
I have a time-series spreadsheet with daily data (some entries are missing) covering 8 years. The x-axis is date and the y-axis a measurement going from 0-1000. I would like to plot the data on a yearly basis, ie x-axis goes from January-December. And I would love to get yearly averages. Is there an elegant solution to do this?
thanks a ton!

Hi Felix,
Do you mind sharing a data file?
Thanks, Snow |

Exactly. it's doable in Origin but cumbersome as you said.
We are trying to improve in how to plot graph in same period, e.g. can be daily, monthly, yearly, etc. but not limited to date/time x. can be for other kinds of x with repeated patterns. Not sure what's a good name for such graph.
Thanks, Snow

I am measuring e.g. water use over time. Every day (almost) I am reading the meter and subtract the reading from the day before. This gives me how much water was used on a particular day. Date is x, daily water use is y. This gives me a good idea on what is going on over the years. There are obviously seasonal fluctuations and maybe long-term trends. To see whether water use over the years changes and if so during which season, it would be cool to show the data as Jan-Dec on the x-axis, on Dec31 2022 at the end of the x-axis, it simply wraps around to Jan01, 2023 at the start of the x-axis. The very same x-axis location where the Jan01 2022 data started.
Note that since not all measurements were made or recorded, I cannot simply use 365 measurements/year. Also, I might want to start with July1 if I am looking at consumer data and the fiscal year starts on July1.
Does this make sense?
You gave me some work-arounds which worked but were not ultimately just very cumbersome.

I suppose you have XY data with x of multi-year date, u want to plot y as multiple plots from e.g. Jan 1st to Dec. 31st no matter which year it is?
Do u just want to plot them to visually compare same period of different years or u want to do some further analysis on them? If so, what analysis.
Thanks, Snow

Hi Snow,
happy to share, but not sure what you want me to share?

Hi Felixs,
Do you mind sharing your data since i don't see the unevenly spaced data warning even if i delete some rows of XY or only delete some Y data.
Meanwhile here is another way u can try:
Extract year info. to a new column C.
Then use Analysis: Data Manipulation: Reduce Duplicate X menu with C as X and B as Y.
We use Julian date for date value so year info. will be considered when plotting graph. So it can't plot multi-year into 1 year's axis range.
Thanks, Snow |

Reduce by Group.
Set Subgroup method as By X Increment, e.g. 1 year

Then plot the result.

Dear Snow,
thanks for this pointer! It is almost what I want. Unfortunately, some of my data are missing, which trips up the unevenly spaced data warning, probably because it does not know how to deal with the average. I am fine with some months/years having fewer data entries than others, do a conditional average would do just fine (add to sum if a number and divide by # of existing datapoints).
So to reformulate as a slightly downsized question, can I plot multiyear data where the x-axis is days/months only and does not take into account the year?
