Emoncms blank graphics

Hi All

I was trying the emoncms, I managed to create some feeds and upload power data (I upload data every 60 seconds) but when I try to view the "Realtime data" graph, it appears blank, same problem with the others graphs, what can be the problem?

Thank's Valerio

If you look at the inputs tab, is there a value for the channel you're interested in and is it updating? If so, you should just need to select the channel, choose 'log to feed' and 'CREATE NEW:' with a name (doesn't have to be the same name as the input channel). Then the feeds tab should show this new name and realtime graph should update.

Incidentally, if you pick a name with spaces, when you put the feedid in a graph, you need to replace the spaces with '-' symbol

Yes

choose 'log to feed' and 'CREATE NEW:'

Done: for now I have 2 feeds: "import-ltf" and "export-ltf" - Inputs are two: "import" and "export"

the feeds tab should show this new name and realtime graph should update

Unfortunately does not happen (blank graphs) :(

Finally I found the problem, I discovered that it run correctly on "localhost" but not on the server ehere it doesn't display graphs running on google chrome, but it is ok on "internet explorer" and "firefox".

After some more research I found this topic http://openenergymonitor.org/emon/node/871 wher the bug was fixed, it was a problem on Models/feed_model.php, a problem of floating point values!

The fix is not actually updated on the downloadable cms! :)
