Viewing

Data visualizations in MathJet are dynamic and highly interactive. This page covers the commonly used viewing operations — rotating, panning, and zooming a chart, plus changing the overall view scale of the visualization scene.

To make viewing as convenient and intuitive as possible, MathJet defines several special modes for different operations. Enter or switch among them with a tool button, by pressing a designated key on the keyboard, or using a specific mouse gesture. The same patterns apply to both 2D and 3D charts.

Rotation

Enter rotation mode by clicking View → Rotation or the corresponding tool button, or by pressing and holding the Alt key. Once in rotation mode, drag the mouse anywhere inside the chart to change the viewing angle. Click the same menu / button again, or release Alt, to exit.

Alternative: press and hold the right mouse button and drag — works any time without entering rotation mode explicitly.

Panning

Enter pan mode by clicking View → Pan or the tool button, or by pressing and holding the Shift key. Then click and drag with the left mouse button to shift the view.

Alternative: press and hold the middle mouse button and drag — works any time, no mode change required.

Zooming

Several ways to zoom, all of which work in both 2D and 3D:

Freehand zoom mode — click the menu option / tool button, then drag the mouse upward to zoom in or downward to zoom out.
Mouse wheel — scroll up to zoom in, scroll down to zoom out. The axes auto-adjust so the point under the cursor stays at the same position on the screen.
Rectangle zoom (2D charts only) — draw a rectangle directly on the chart. The corners of the drawn rectangle become the new viewing range for zoom-in; for zoom-out, the currently displayed range is fit inside the drawn rectangle.

Axis-restricted panning and zooming

By default, panning works in any direction and zooming applies the same factor to all axes. To restrict an operation to a specific axis:

Hold x, y, or z during panning or zooming to limit the operation to that axis.
Drag the mouse along an axis line, outside the chart area, while in pan or zoom mode — limits the operation to that axis.
Hold Ctrl and drag along an axis line to define a precise viewing range along that axis.

Hotkeys for transitory operations

Several hotkeys apply common view changes without entering a mode:

Key	Action
F	Fit All — restore default ranges to show every data point
G	Fit Selected — set viewing ranges to only the selected data points
H	Reset All — restore both ranges and viewing angles to defaults
s	Default 3D viewing angle (3D charts)
w	Top-down view (3D charts)

(Additional orientation hotkeys are available for 3D charts; see the on-screen reference for the full list.)

Overall view scaling

A slider in the status bar adjusts the overall scaling factor for both plot windows and spreadsheets. Useful for switching between a close-up and a bird’s-eye view of the visualization scene without touching individual chart axis ranges.

Viewing operations — rotation, panning, zooming, axis-restricted variants, hotkeys, and overall view scaling across 2D and 3D charts.
