The data (online and offline or green and red or 0 and 1) would be stored as a google sheets file.
Do you know a stacks that will allow me to do this?
Thank you
It would take a bit of creativity using Charter but you could perhaps use something like a bar chart:
Another option might be to use a series of small Pie Charts - though that would require a separate Charter stack and Google sheet for each which would likely be more trouble than it would be worth.
