baseline = "baseline",
col = 1:length(history),
alpha.f = 0.7,
bw = 3600 * 24,
by = 4,

## Arguments

history list of the submissions history per team as returned by compute_metrics string. name of the team considered as the baseline that will not be plotted. colors of the teams. factor modifying the opacity alpha of colors; typically in [0,1]. real. the smoothing bandwidth to be used by density in seconds. real. height of the interval between two teams in nb of submissions. axis labels. see title. graphical parameters. see par. the color used for the legend text. see legend. further parameters passed to plot function.
