A minimalistic and customizable graph card for Home Assistant Lovelace UI.
The card works with entities from within the sensor domain and displays the sensors current state as well as a line graph representation of the history.
Please visit the GitHub repository for installation and usage instructions.
Setup and running, no errors in the log, Thanks!
Oh, that’s great.
Love your setup, thanks for trying it! 
Another great card! Thank you very much!!!
My gosh that is a sexy card! Love it in the UI, thank you so much for making it!!!
Amazing I have tried graphs in the past and didn’t like the look and feel of them. Will be trying these out in the morning cheers.
This is really cool.
Any chance of being able to combine multiple entities on the same chart? For example multiple Temp sensors with a mini legend to identify the different colours?
That should certainly be possible, I will consider that feature, thank you!
Great job. Thank you.
Is it possible to add a choice of custom backgrounds or colors for the card?
Haven’t got the time to try it out yet. But i definitely will do!
Great work. Thats a totally awesome and needed card

and ofc the 2 files in www-folder:
i have dat but no graph, look here:
what do i do wrong?
Thx in Advance
Strange, the graph and icon is not visible? What version of HA are you running? Do you get any errors in the log?
Getting this issue too 
Two of my sensors (in the bottom of the picture) that are Xiaomi Bluetooth ones sometimes presents a graph for a few seconds, but on refresh it’s just gone. No problems with my zigbee ones, the only difference i can come to think of between them is that the bluetooth ones are reporting temperature a bit sporadicly, sometimes every 5-10 minutes, sometimes it could be 40 minutes, but i still get a native graph in the UI and the latest temperature is always displayed. Running 0.79.2 with the latest Mini graph card on a RPI 3. The only error in the log is this:
2018-10-04 23:03:21 ERROR (MainThread) [frontend.js.latest.201809270] https://fillwe.duckdns.org:8123/lovelace/2:0:0 Uncaught
The log is empty,
and i am Running 0.79.1 at the moment
Strange is, that i thought, in one graph i saw shortly a red line, but it was gone after refresh!
The second strange thing is, that the data comes from one single entity, a Tasmota POW !
A fault from my side?
Thx

Ughh, wish I had more sensors to debug this issue with, haven’t seen it myself.
No, it’s most likely an issue with the card, I’ll try to figure it out.
Can any of you please check the developer console in the browser for errors?
I had the same issue first time and it was because the recorder component didn’t have the domain added so there was no tracking of the information. Once I added it (and wait a little) I started to see the chart.
Hi, this is really nice one! And could you please share you’re dark theme? Still can not find satisfying look.
This is great information, thank you.
Thanks! sure, here it is:
No, unfortunately since the design is somewhat responsive, setting a fixed height is not possible, although you can however manipulate the height in some manner with the height option.
