JitterPlot
(**traits)¶ Bases:
chaco.plots.scatterplot_1d.ScatterPlot1D
A renderer for a jitter plot, a 1D plot with some width in the dimension perpendicular to the primary axis. Useful for understanding dense collections of points.
-
get_screen_points
()¶
-
jitter_width
= Int(50)¶ The size, in pixels, of the area over which to spread the data points along the dimension orthogonal to the index direction.
-
map_index
(screen_pt, threshold=2.0, outside_returns_none=True, index_only=True)¶ Maps a screen space point to an index into the plot’s index array(s).
-
map_screen
(data_array)¶ Maps an array of data points into screen space and returns it as an array. Although the orthogonal (non-scaled) axis does not have a mapper, this method returns the scattered values in that dimension.
Implements the AbstractPlotRenderer interface.
