Added
- documentation
- graph config attribute size_y: specifies y tick size
- graph config attribute precision_y: specifies y float precision
- graph config attribute sizes_x: specifies valid sizes for the x axis (this is currently not properly
supported, and currently will only respect the one size that actually matches the timestamp gap in the
graph data)
Fixed
- fixed an issue where using an id field other than "avg" would cause the graph not to render
