When plotting a continuous stream of integers the rolling chart will not chart zeros and instead place a gap whenever an attempt to do so is made.

This is clearly caused by line 74 in /lib/charts.js

data[k].push(message.values[k] || null);

I have a local branch with bug fix ready, but I was just wondering if this is maybe intended behaviour?
If not I could create I pull request.

As the title says. If you want to add a data point with value 0, you must enter 0.0001.
The graph won't update with a data point of 0, and will jump leaving a gap in the graph on the next non 0 data point

the Mapping library used in ECA moved from Collections to Collections.abc

The class collections.Mapping has been moved to collections.abc in python 3.3. It has remained possible to use it from collections, but this changed in python 3.10. See "bpo-37324: Remove deprecated aliases to Collections Abstract Base Classes from the collections module." in https://docs.python.org/3/whatsnew/changelog.html. The ECA framework now does not run on Python 3.10. This is easily fixed by changing the imports.

The following changes need to be made (I tried to push them to a branch, but I lack permissions):
Change from collections import namedtuple, Mapping to from collections import namedtuple from collections.abc import Mapping in eca/sessions.py. and changing collections.Mapping to collections.abc.Mapping on line 105 of eca/http.py and on line 124 of eca/_init__.py.
