Hi, I have a problem when I want to create a multigraph or other graph in Visualization module. The graph is empty after I choose the feed. Also I have the same problem when I create any graph in Dashboard, but whit other widget I have not this problem and in graph module I can see historic data feed when I select any feed.
I have a emoncms installation on Debian 10. I followed emoncms/LinuxInstall.md at master · emoncms/emoncms · GitHub guide.
I attached a image which show what I appear when I create a multigraph in Visualization module.
Have anyone the same problem? Can you help me?
Thanks.!
