kplot is a programming library for plotting graphs on a Cairo
|
||||
surface. It handles drawing margins, axis labels, tic labels, tics,
|
||||
borders, grids, and the data itself. Data may be specified structurally
|
||||
as finite buckets, range histograms, arrays, and vectors. Data may
|
||||
also be computed from other sources, such as the mean and standard
|
||||
deviation.
|
||||
|
||||
This version has been patched to work with siril
