3D charts

To draw 3D surface is equally simple, just pick an expression with at least two variables, set ranges for these two and click chart button.

Explicit presentation

This example is a follow up from 2D chart first example with additional range variable (b).

The tool-bar buttons on the left will allow to manipulate the surface (from top to bottom):

• 2D chart-like behavior
• rotate the surface
• increase/decrease the visual depth of the chart
• move around
• zoom-in / zoom-out

Parametric presentation

A 3D curve is define by three expressions (for the three axis) and one range variable.

A 3D surface (or pseudo-surface) is define by three expressions (for the three axis) and two range variables.
