trackpy.plot_traj(traj, colorby='particle', mpp=None, label=False, superimpose=None, cmap=None, ax=None, t_column=None, pos_columns=None, plot_style={}, **kwargs)¶

Plot traces of trajectories for each particle. Optionally superimpose it on a frame from the video.

Parameters:

trajDataFrame: The DataFrame should include time and spatial coordinate columns.
colorby{‘particle’, ‘frame’}, optional
mppfloat, optional: Microns per pixel. If omitted, the labels will have units of pixels.
labelboolean, optional: Set to True to write particle ID numbers next to trajectories.
superimposendarray, optional: Background image, default None
cmapcolormap, optional: This is only used in colorby=’frame’ mode. Default = mpl.cm.winter
axmatplotlib axes object, optional: Defaults to current axes
t_columnstring, optional: DataFrame column name for time coordinate. Default is ‘frame’.
