Interactive parametric curve trimmer with a dual-handle range slider.

Displays a 2D parametric scatter plot alongside an ipywidgets IntRangeSlider that trims which points are shown. Designed for use in Jupyter notebooks.

Parameters:

• x (NDArray[float64]) – X-axis values.

• y (NDArray[float64]) – Y-axis values. Must have the same length as x.

• timestamp_unit (Timescale) – Unit for timestamp labels in the slider. Ignored if timestamps is None. Pass aly.data.timestamp_unit.

• timestamps (NDArray[float64] | None, optional) – Timestamps corresponding to each point, shown in the slider labels. If None, slider labels show index only.

• x_label (str, optional) – X-axis label.

• y_label (str, optional) – Y-axis label.

• title (str | None, optional) – Plot title.

• layout_config (LayoutConfig, optional)

• font_config (FontConfig, optional)

Return type:

ipywidgets.VBox
