Multigraph Timestamps Wrong

Submitted by Esk Energy on Fri, 04/03/2016 - 09:50

Multigraphs seem to change what it displays as a time stamp depending on where the data point is displayed on the x axis.

The attached screen shots where obtained by just scrolling left-right and shows that the blue line timestamp changed from 16:49 to 16:52.

Any ideas why and how to fix it?

The original data can be seen at

(the date was 27/2/16)

Thanks

Just had a look and noticed I could actually see it move: https://www.youtube.com/watch?v=TsykJ4uXlU0

This occurs to our multigraphs aswell, which are on emoncms.org. Not sure if yours are as well, or if you are running your own server.

We're on our own server - check out http://whitbyeskenergy.org.uk under the Generating tab. This graph is on the "Engineering" sub-menu

You can see all the graphs realign themselves slightly but the blue one is most pronounced.

FYI all the lines EXCEPT the blue one are 5 minute data, the blue one is one minute data.

I would love to know how to fix this as we're using this particular graph to analyse a sensor glitch and I need to know the sequence things happened.

Thanks

Update

I've had a look at the data files and they're all timestamped to 5 minute boundaries.
(i.e. the meta files start times are all seconds=0 and minutes multiples of 5)

The attachments in my first post show "non-5-minute" time stamps

So the question is why is multigraph getting the wrong time and why does it move?

Thanks
