The panner window

This window always shows a full view of the spectra displayed in the related plot. It is designed to allow you to pan around the full sized view by moving the red rectangle.

The display is always drawn at the same aspect ratio as the full sized display, but is scaled to fit within the width or height of the panner window. Because of this there may be better widths or heights to fit any particular zoom. Resize the window to gain familiarity with this feature.

The following mouse interactions are provided:

• Centre display area, to centre the display area just put the mouse pointer over the panner and press the left mouse button.

• Scroll display area, to scroll the display area you need to drag the red rectangle. To do this just place the mouse pointer in the red rectangle and then press the left mouse button down, now move the mouse to drag the rectangle. When you're finished release the mouse button.

• Zoom display, to zoom the main display by a factor of 1 in X, just press the middle mouse button.

• Unzoom display, to unzoom the main display by a factor of 1 in X, just press the right mouse button.
