problems when using multigraph

Submitted by Eric_AMANN on Mon, 03/02/2014 - 13:02

I am facing problems when using multigraph, both on Emoncms.org and on my local server (V7).

Sometimes, I get a blank graph when loading a dashboard containing a multigraph. Sometines, some feeds are missing.

To get the multigraph works fine, I have to reload the page or to click on the D (or W or Y) buttons several times.

Most of the time, I lost the feeds when using the +/- (or </>) buttons) or when zooming in (focus with a window).

My browser is Mozilla Firefox Ubuntu 26.0.

Try this Eric,

Go to Vis and load up the multigraph that you have used in the dashboard.
In the multigraph preview on the right hand side, select the default view that you want to see in the dashboard. For example click 'D'
Save the Multigraph.

Now every time you open the dashboard you should see 1 day's worth of data by default.

In respect of the disappearing feeds, could it be that you are zooming in too far? You will need at least 2 feed datapoints on screen for a line to be drawn, and if your feeds update less frequently, or you have missing datapoints, it's easy to zoom in and have just one datapoint in view - and therefore there would be no feed evident in the graph.

I am seeing a similar phenomenon with my graphs as well. They do not load with data and I need to hit D W etc. to display data. This is something that has started just recently. I even see this on some of my raw data graphs on my dashboards.

David, have you tried the above?

Hi Paul,

I created my multigraphs exactly how you told me to do it but it doesn't change anything. Sometimes I get a blank graph. Sometimes, one or several feeds are missing. To reproduce that bug, you can access to my main dashboard and reload that pages 10 times.

When I zoom in, I don't go too far. (2hours=120 data). Sometimes it works but some others times, I got a blank graph.

These two bugs must be related neither to my emoncms account nor to the way I created my multigraphs because I also got them when accessing public dashboard that belong to others emoncms.org users. Not sure, but It seems to be pretty new.

EDIT : I do not select the option "published" for my dashboard. What does this option mean for a dashboard ?

Take a look at the Dashboard Configuration part of this page of the Emoncms guide for what published means

http://emoncms.org/site/docs/dashboards

Can you also see if you have the same issue in a different web browser such as Chrome.

Paul,

I did try the suggestion above, but it did not resolve the issue. I did forget to mention that I am using Chrome as my web browser. Everything was working perfectly until just recently.

I've attached a screenshot of one of my dashboards. The top graph is a raw data graph and the bottom is a reat time graph. If I click one of the buttons on the graph, the data will show up. The dials update just fine.

Same observation on my side. It is a pretty new wrong behaviour.
