Is your config published somewhere? I can try to fix the problem then.
Hi Happy Leaves,
I forgot to thank you for your great work.
The panel shows up in in Home Assistant and so does the graph, it is just the zooming that does not work.
I copied the svg-pan-zoom.min.js file straight from GitHub and created the HTML file with your example using Notepad++. I have run chmod 777 on all the files just to make sure it is not a permission issue.
Do you think it could have something to do with NGINX?
Make sure that HTML file is correct. The error you pasted makes me think there’s a problem there, since it is a syntax error.
So I am assuming that I need to setup nginx to be able to access it remotely? I dont have that set up and I am getting localhost refused connection errors.
If so does anyone have an nginx for dummies link? It seems to be way over my head
Think I copied the wrong content for svg-pan-zoom.min and after correcting it Chrome kept it in its cache even after me clearing it, not sure but it is working now! I also upgraded to 0.39.2 but I doubt that has any influence/
Thank you so much!
NGINX is not required, you can expose Home Assistant directly onto the internet if you want.
I am running NGINX on Ubuntu but it should be the same on the Pi. The first time I did set it up was with this guide: www.htpcguides.com/secure-nginx-reverse-proxy-with-lets-encrypt-on-ubuntu-16-04-lts/
However have a look at this guide:
And https://objectpartners.com/2016/05/26/setting-up-nginx-and-ssl-for-home-assistant/
You do not need NGINX. The file is served via Home Assistant.
I guess I might need some help then. I created the www directory and added the files and added the following to my panels_iframe.yaml
graph:
title: "Graph"
icon: mdi:vector-polyline
url: "http://localhost:8123/local/graph.html"
I tried changing localhost to 127.0.0.1 and had the same result which is a greyed out ipanel that says “localhost refused to connect.”
The chrome console shows:
Uncaught (in promise) DOMException: Only secure origins are allowed
Failed to load resource: net::ERR_CONNECTION_REFUSED http://localhost:8123/local/graph.html
However, I tried in Firefox and have the same issue.
Are you running chrome/Firefox on the local machine? You are now linking to local host which only works if on the local machine. It might be better to replace local host by the IP address of your homeassistant server.
I’m receiving this error:

Can you share your scene? It’ll be one that doesn’t have entities in it.
Well, your question made me find it right away 
I have a bad habit of typing “entites” instead of “entities”…
Thanks!
Hi,
This looks awesome nice work.
I am trying to set it up for myself. I am running Hassbian.
graphviz graphviz-dev installed successfully but when i try pip install hagraph i get the following

not really sure how to sort this out. apologies for the long post i wasn’t sure what needed to provide.
Try pip3 install hagraph, or make sure you’re in a python3 virtual environment before using pip.
With this command:
pi@raspberrypi:~ $ python3 -m hagraph -i /home/homeassistant/.homeassistant/configuration.yaml -o /homepi/graph.pngI get the following error:

First, i should say thanks for the hint of using the virtual environment to install hagraph it worked. I had to open the shell as homeassistant user to get permission to install it, though.
(homeassistant) homeassistant@hassbian:/home/pi $ python3 -m hagraph -i /home/homeassistant/.homeassistant/configuration.yaml -o /home/homeassistant/.homeassistant/www/graph.svg
produces:
THIS IS AWESOME…
The panel is displaying correctly however the shell command doesn’t produce graph.svg when it is called. i deleted the image manually then tried firing the command from within HA but no luck it only works when i login as homeassistant user with a virtual env over ssh
Thanks i just got errors when i attempted to install hagraph but with pip3 worked. Thanks for posting it.
Thanks for sharing this i can see my graph now. Let’s see if i can make it zoom in.
Sorry for a beginner’s question how do i add the zoom?
Thanks
Assuming you got the graph working I take it that you used the HTML from Happy Leave`s Github? In that case download the svg-pan-zoom.min.js from here https://github.com/ariutta/svg-pan-zoom/tree/master/dist and put it in the WWW folder. Clear the cache in Chrome or whatever browser you are using and you should be good to go.
Thanks
That deed the trick, now all works fine.
Thanks again.
