A brief note on terminology as used here: a "graph" is a plotted screenful
of data, showing the results of one type of test: for example, the
page-load-time graph. A "trace" is a single line on a graph, showing one
one for the test: for example, the reference build trace on the
page-load-time graph.
This page plots arbitrary numerical data loaded from files in a specific
format. It uses two or more data files, all JSON-encoded:
graphs.dat: a list of objects, each with these properties: name (the name
of a graph) and units (the units for the data to be read by humans).
Schematically:
[{"name": <graph_name>, "units": <units>}, ...]
<graphname>-summary.dat: for each of the graphs listed in graphs.dat, the
corresponding summary file holds rows of data. Each row of data is an
object with several properties:
"rev": the revision number for this row of data
"traces": an object with several properties of its own. The name of
the property corresponds to a trace name, used only as an
internal identifier, and the property's value is an array of
its measurement and that measurement's standard deviation (or
other measurement error).
Schematically:
{"rev": <rev>,
"traces": {<trace_name1>: [<value1>, <stddev1>],
<trace_name2>: [<value2>, <stddev2>], ...}
}
