multi-key-graph is a command line tool that invokes matplotlib to plot multiple keys on multiple graphs from an FSDB/pyfsdb data file (tab-separated with a header).

pip3 install multikeygraph

multi-key-graph is designed to:

1. read in time-series data in FSDB format
2. Plot data in columns (-c COLNAME1 ...) for a given key column value (-k KEY).
3. Which key values to be plotted can be limited to a fixed list (-l VAL1 VAL2 ...)
4. Save the results to an output PNG file (-o OUT.png) or a window (-i)

If multiple columns are specified, the output will contain multiple vertically stacked graphs with aligned X-axes allowing for easier comparison of noisy time-series plots.

Plot labels can be specified using -T TITLE, --xlabel X-LABEL, and --ylabel Y-LABEL. By default line plots are drawn, unless a dotted/scatter plot (-s) is requested. Data should be pre-sorted for line graphs.

A list of name=replacement values can be passed for legende name replacements (-L name=replacement). Anonymization of key values may be specified with an anonymization pattern that includes a %d specifier (-A "some%d").
