Hi,
Just upgraded to 8.0 this morning from 6.0 (no redis). I disabled redis in the settings.php file as this gave problems. Overall the upgrade went well, but the zoom visualisation no longer works (doesn't show any data except for the current value). The simplezoom and other visualisations seems to work just fine, so acces to timestore and the db are ok. Also tried clearing the cache several times with no result.
I'm now wondering if this is related to disabling redis or because I skipped the V7.0 upgrade (the db check only created a node and myelectric table) ?
Re: emoncms v8.0 - zoom not working ?
Found out that that the zoom visualization sets $dp = 0 which makes the function get_data in feed_model.php fail at a divide by 0 error. Moreover, $start and $stop are not correctly initialized and are both zero. Opened a new issue on github as I don't know the code that well to figure out a fix.

Thanks for finding this, its now fixed and pushed up to git master it was an issue with the mysql get_data implementation not working correctly for daily data.

For those who may be using the debian packaged version already, this is included in version 8.0.1
