Hex's Logic View is based on the popular notebook format. If you have used a Jupyter or similar notebook, you will be right at home.
Hex, however, extends the notebook model in some key ways:
The outline provides an easy-to-browse overview of all the cells in a project's Logic View. Every cell in the outline lists the variables it defines, and cells that return a displayed output (chart cells, Input Parameters, markdown cells, etc.) display a preview of that output. You can click any cell in the outline to automatically jump to that position in the logic.
The outline can also be filtered to display only markdown cells for a "table of contents" style view, or only Input Parameters for a "control panel" style view.
Input elements in the outline are fully interactive, allowing you to adjust upstream parameters without excess scrolling.
The outline is a key element when building an app. We'll cover it in more detail in the App Builder section.
Cell outputs, like charts or tables, are given default output names (e.g., "Output 3") but you can rename them by clicking the name anywhere it appears.
Custom output names will then appear as labels in the App Builder:
