More heating work

One of my objectives with the automated heating system was to be able to record how much we use the heating, and so I record all on/off events in a logfile. In order to visualise the data I went looking for a free chart component for c#.

I found ZedGraph, which is a sourceforge project for "creating 2D line and bar graphs" - exactly what I wanted. I spent some time writing code to parse the file into time events, and adding new commands to the server to retrieve the data.

I knocked out a quick GUI, which is not fully functional yet, but it demonstrates what I want to see.

Below is a screenshot of a graph for December so far...

For some reason the graph always leaves the first label off the x axis, but thats really only minor in the grand scheme of things!
