Table Shape
The Table shape displays computed values from your model, allows manual data entry, and provides cell selection for performing regression analysis.
Overview
A Table shape shows the value of selected terms at each iteration step. It can display both computed columns (from expressions) and user-entered data columns. Tables are essential for data analysis workflows — you select cells, apply regression, and see results in linked charts.
Toolbar

The Table toolbar provides:
- Column picker — Choose which terms to display as columns
- Add data column — Add a manually-editable column
- Regression method — Apply regression to selected data
- Color picker — Change shape accent color
- Delete — Remove the table from the board
Column Types
| Type | Description | Editable |
|---|---|---|
| Computed | Values calculated from model expressions at each iteration | No |
| Data | User-entered values for experimental or reference data | Yes |
| Regression | Column generated by a regression fit | No |
Cell Selection

To perform regression analysis:
- Click and drag to select a range of cells in a data column
- The selected range is highlighted
- Choose a regression method from the toolbar dropdown
- The regression result is created as a new term in the model
Select cells from two columns (X and Y) to define which data pair to use for the regression fit.
Regression Methods
| Method | Fit Function | Output |
|---|---|---|
| No Regression | — | Clears any existing regression on the selection |
| Linear | y = ax + b | Creates a regression term with slope and intercept |
| Quadratic | y = ax² + bx + c | Creates a regression term with quadratic coefficients |
Working with Regression Results
When you apply a regression:
- A new term is created in the calculator (type: REGRESSION)
- The regression curve can be displayed in a Chart shape
- Outlier data points are automatically detected
- The regression parameters (slope, intercept, etc.) are available as term properties
See Regression for a full workflow guide, and Outliers for how outlier detection works.
