You can read lots more about control charts here.
You can read the docs about the library here.
Or, just call the service URL with your data:
http://spc.io/?data=1,2,3,4,5,6,7,8,9,10&ouput=png and it will send back something like this:
from spcchart import SpcChart data = [1,2,3,4,5,6,7,8,9,8,7,6,5,5,5,4,4,3,3,2,2,2,3,4,5,5,5] c = SpcChart(data, title="Flow Ho") c.render()
