Data Source Window
The Data Source Window lists currently-open data sources: external data files and connections to databases. The visual layout mirrors the Environment Window — same cell blocks, same optional statistics, same drag-and-drop into spreadsheets — so the muscle memory transfers directly.
Features
Section titled “Features”Collapsible tabular views of values
Section titled “Collapsible tabular views of values”Detailed numerical values from open data sources are shown in a tabular arrangement using ordered cell blocks. Drag a variable cell block into a spreadsheet data widget, or create it directly inside a spreadsheet.
A cell block represents a rectangular area of related cells, managed and referenced independently from the rest of the data source. Cell blocks are views — not separate data entities — so changes to the underlying value are reflected immediately.
Flexible data layout
Section titled “Flexible data layout”- Scalars are shown adjacent to their name in the header row.
- Arrays, lists, dataframes are summarized in the header, with full numerical values revealed via an expansion button. Layout is rows or columns, auto-determined or user-specified.
- High-dimensional values can have child blocks inside the parent block’s body.
Sparklines and descriptive statistics as column headers
Section titled “Sparklines and descriptive statistics as column headers”For values with more than one row, columns can display sparklines and descriptive statistics as their headers.
Large collection of table styles
Section titled “Large collection of table styles”Apply table styles for the visual treatment you want. Beyond conventional banded styles, MathJet offers options that encode numerical values as cell background or foreground color for quick visualization.
Options
Section titled “Options”Filter list and values
Section titled “Filter list and values”Two filtering modes via the Filtering Operation Type sub-menu:
- Filter List by Name — only items whose names match the keyword in the Filter text box are visible.
- Highlight Values — items whose values match the criterion are highlighted yellow; the rest are greyed out.
In Highlight Values mode, the criterion is auto-determined (e.g.,
0.5:1.5 becomes “between 0.5 and 1.5”) but can be overridden via
Filtering Condition.
Matrix layout for multi-dimensional data
Section titled “Matrix layout for multi-dimensional data”Pick from Hierarchical 2D Matrices, Continuous 2D Matrices, Continuous Rows, Continuous Columns, Single Row, or Single Column — same set of options as in the Environment Window.
Enable / disable data outlining
Section titled “Enable / disable data outlining”Data outlining (expand / collapse on each item) is on by default and can be disabled.
