Overview Window

The Overview Window provides a visual synopsis of whatever data object currently has focus — a spreadsheet, a data table, a column, a chart, a graph, a code editor, a variable, or a link to an external data source. It refreshes automatically based on recent user interactions, so the visible synopsis is always relevant to whatever you’re working on.

Features

Dynamic content update

The program dynamically determines the focus data object from recent user interactions and instantly refreshes the Overview Window to display the most relevant visualization of that object. The visual display adapts as the user works — no manual refresh, no stale view.

By default, when the user interacts with objects inside any data widget directly, the system prioritizes the display of objects lower in the data visualization hierarchy to ensure relevance. For example:

Selecting a cell within a data table shows that table — not the spreadsheet in its entirety.
Engaging with a specific chart among several inside a chart sheet triggers a focused display of that chart, reflecting its status as a child of the sheet.
Clicking a tree node in the Workspace Manager shows the visual representation of the associated object. If the object is too low in the hierarchy (e.g., an individual graph inside a chart), the closest parent in the hierarchy — the containing chart — is shown instead.

Adapts to the focus data object

The visualization style automatically matches the kind of object in focus:

Cell range — every cell rendered as a small rectangle, with text shown as filled rectangles when characters are too small to be individually legible. A draggable rectangular marker indicates the cells currently in view in the spreadsheet.
Data table — values displayed as a heatmap in a color-coded grid, with the same draggable marker indicating the visible region.
Table column / numeric variable — values plotted as a line graph.
Two-dimensional matrix variable — displayed as a heatmap, with a marker linked to the visible region of the corresponding variable cell block in the Environment Window.
Chart sheet (multiple charts) — an all-encompassing view showing every chart on the sheet.
Single chart — the chart redrawn with auto-adjusted axes that include every data point, even ones outside the visible frame in the main widget. A rectangular or wireframe marker indicates the region currently visible.
Code editor — a comprehensive snapshot of all code in the file, with a draggable rectangle marking the portion of text currently in view in the editor.

Draggable range marker

When the focus widget displays only a portion of the underlying data (zoomed in, scrolled, or partial column visible), the Overview Window draws a resizable rectangular marker (or wireframe box for 3D charts) over the synopsis to indicate the visible region. Drag the marker to scroll the linked widget to a different region — a quick way to navigate large data sets without leaving the focus widget.

Manual focus override

Although the Overview Window refreshes automatically by default, the user can also manually select which summary visualization to display, overriding the auto-determined focus.

Gallery view of all data widgets

A special Gallery view option displays every open data widget as a small icon image. Double-clicking any icon activates the corresponding data widget; the Overview Window then automatically switches back to that widget’s visual summary. Useful for jumping between many open documents without scanning tab labels.
