5. OutlierRejection#

class OutlierRejection(ax: Axes, data: ndarray, plot_type: str = 'scatter', bins: int = 20, marker: str = '.', label: str = '')#

WORK IN PROGRESS

Handles the selection and removal of the outliers points from the plots.

Allows the users to select a set of points using the lasso selector and remove them.

Attributes

`ax`	Axes object of the plot.
`canvas`	Canvas attribute of the plot.
`data`	Data array for scatter or histogram.
`label`	Label for the plot.
`lasso`	Lasso object to handle the mouse events.
`marker`	Marker of the plot.
`removed_indices`	List to save the indices of the outlier points
`scatter`	Scatter plot object.

Methods

`apply_lasso`(ax, data, plot_type, label[, ...])	Applies the lasso selector to a single plot and returns the removed indices.
`onselect`(coords)	Handles selection of histogram bins or scatter points for removal using lasso.
`set_outliers`(json_file_path)	Updates the outlier flag in a JSON file for specified indices.
`update_plot`()	Updates scatter plot by removing selected points.

static apply_lasso(ax: Axes, data: array, plot_type: str, label: str, marker: str = 'o', bins: int = 20)#

Applies the lasso selector to a single plot and returns the removed indices.

Parameters:

ax (Axes) – Matplotlib Axes object.
data (np.array) – Data array for scatter or histogram.
plot_type (str) – Type of plot (“scatter” or “histogram”).
label (str) – Label for the dataset.
marker (str, optional) – Marker style for scatter plots (ignored for histograms).
bins (int, optional) – Number of bins for histogram (ignored for scatter plots).
