Zoom

Zoom in​

To zoom in, click and hold the left mouse button, drag to highlight the region of interest, then release. Repeat the same action to zoom in further.

Zoom out​

Double-click anywhere to return to the previous zoom level; double-click again to step further back. NMRium remembers all zoom levels.

You can also scroll the mouse wheel to scale the spectrum vertically.

Click the "zoom out" icon once to zoom out horizontally, or twice to zoom out both horizontally and vertically.

Vertical zoom​

When the mouse cursor is over the 2D part of the spectrum and you turn the wheel of the mouse, you can change the vertical size of the spectrum. If the cursor of the mouse is over the 1D part of the spectrum and you turn the wheel, the size of the 1D part changes.
