How to load historic data and show in graphs

[johnpolak]

Hi All

Forgive me but I am new to WeatherCat and can't as yet find an answer to any of the following queries in the user manual or on the forum.

I connected my Vantage Pro 2 Data Logger to WeatherCat for the first time two days ago, but it didn't download any historic data (even though I know the Data Logger would have been full). It only started recording data from the time of the first connection. Is there a fix for this - or did I do something wrong?

Also, I can't seem to work out how to create custom graphs using historical data for specific date periods. E.g. How would I look at, say last December's external temperatures in a graph. The only option seems to be to create a graph for the current month, week or day etc. Also, is it possible to overlay two months in a graph for comparison, for example External Temperatures from November 2014 v November 2015?

I know WeatherLink can do this - but perhaps WeatherCat doesn't as yet have this capability? Again, forgive me if i have missed something in the manual - but I can't see it anywhere!

Any help appreciated!

Regards John.

I'll tackle your first question. You didn't do anything wrong. The data logger only starts recording data for WeatherCat from the time of the first connection. A few users have tackled importing data manually from pre-WeatherCat files. Hopefully one of them will chime in here. In my case, I just decided to start over with WeatherCat data.

Blick is correct, it'll ignore anything in your logger prior to its first run, thereafter it'll download as needed.

WRT the graphs - both of these are on the feature request lists - it currently isn't possible to either plot stuff from prior years or comparative graphs.

Thanks Guys. That will at least save me more fruitless searching!
