I think it will be really cool to have a module which will render a graph from the values you provide. Let’s say it will be a txt file or url with values put into rows. So the module will grab last N rows and render a graph.

All ideas I have for now is to create a transparent graph image myself and import it with the RandomPhoto module.

Im wondering do anyone here tried to create a custom graph for MM?

@feedparakeet For such a basic functionality we should not reinvent the wheel. There are a lot of javascript graphing libraries available which are far more sophisticated than anything we will be able to code for the mm in a reasonable manner. They usually render the result in a canvas which can simply be added to the mirror e.g. http://www.chartjs.org/

Thank you for a reply! When I was talking about a function that will render a graph, I was talking about a module that will render a graph, my mistake. ChartJS looks amazing, still I never coded in javascript and that’s why Im dreaming about a complete module for mm.

And yes, I also thought about a transparent image with a graph that can be loaded into mm screen. For example, I can run a script which will create a graph image which will be available throw some url and show it on the mm screen with a https://github.com/diego-vieira/MMM-RandomPhoto module that will refresh it from time to time.

I just started working on this, creating some functions to render graphs.

Yawns, great to hear! Any updates with graphs render for the Magic Mirror ?
What Im dreaming about is a universal graph render function which will take values from a text file, like, last 100 rows and will draw a graph. Or it can be a rss feed.
