Zoom and Pan in the Visualisations

When the mouse is placed in the spectral visualisation area, thecursor will change to a magnifying glass and two sliding bars (with adefault colour of dark green) appear above and below the displayarea. The latter indicate the region that will be zoomed if the mouseis left-clicked and will follow the left and right movement of themouse. To zoom out you only need to right-click. The samefunctionality can be achieved if your mouse has a scroll wheel.

If the display is zoomed, the spectral area beyond the boundaries ofthe viewing window (and therefore invisible) may be brought into viewthrough the use of the panning function. This is achieved by movingthe mouse into the green sliding bars. The cursor will turn into ahand symbol and the bars can be grabbed and the display moved to theleft and right.
