Anybody succeeded using Plotly?

I am trying to use the API for Arduino on plot.ly using the example program. I got it to compile, and my Wifi-shield seems to be working. But I see no new data file appearing on the plotly side. The serial monitor just keeps saying

connected to server
closed connection with server

I did not find anything about plotly in this forum. Is anybody using it with Arduino?

Plotly now also has an ethernet library. It worked without problems.

And now I also saw that the Wifi example sketch did work two weeks ago. It just took some time for my data to show up in my account, under the "My Files" tab. I am looking forward to use this service, because their plots look really great.

These guys are amazing. Tonight I found out that their example file did not work with the Due (although it did work with my Uno and with my Mega). They solved it within a few hours, on a Sunday night. Thank you Chris! Now it is easier for me to use this with a 3.3-volt sensor.

Plotly gave me access to a new version of their Arduino library, which allows for multiple traces and a time axis.
I am alpha testing here: Växjö GPS monitor.

Also on my side, this is a work in progress.
