widgets.py — DatasetWidget: compact per-series panel

class pygra.widgets.DatasetWidget(dataset, color, on_duplicate=None, on_replot=None, parent=None)[source]

Bases: QWidget

Compact per-series control panel embedded in the left tab widget.

Shows dataset name and dimensions, a histogram-mode toggle, column selectors for x, y, dx, dy (line mode) or a single column (histogram mode), an Appearance button, a duplicate-series button, and a visibility checkbox. Style details are edited through AppearanceDialog or HistAppearanceDialog.

Parameters:

  • dataset (DataSet) – The dataset this widget controls.

  • color (str) – Initial hex color string for the series (e.g. "#1f77b4").

  • on_duplicate (callable, optional) – Called with dataset when the “Add another plot” button is clicked.

  • on_replot (callable, optional) – Called with no arguments whenever a style change requires a full replot.

  • parent (QWidget, optional) – Parent widget.

set_mode(mode)[source]

Set display mode programmatically.

Parameters:

mode (str) – One of "series", "histogram", or "hist2d".

refresh_col_ranges()[source]

Update the maximum value of all column spinboxes.

Should be called after the underlying dataset gains or loses columns (e.g. after a transform operation adds a new column).

get_config()[source]

Return the current widget configuration as a plotting dict.

In series mode the result includes series-style keys; in histogram mode it includes histogram-style keys; in hist2d mode it includes hist2d-style keys.

Returns:

Keys always present: "label" (str), "visible" (bool), "hist_mode" (bool), "hist2d_mode" (bool), "xcol", "ycol", "dxcol", "dycol", "hcol" (int). In hist2d mode "xcol" and "ycol" reflect the hist2d column spinboxes. Additional style keys are merged from the active style dict.

Return type:

dict
