Frequency and Intensity:               
Instructions:
* The spectrum amplitude at the current mouse position is printed above the spectrum box. The corresponding point on the spectrum is shown in pink.
* The vertical position of the mouse during a click or drag does not matter. While dragging, do not position the mouse on the blue spectrum curve. Only the horizontal position is used.

1. To expand the horizontal scale (two methods):
- Drag using the mouse on the spectrum.
- Enter the plot extremes into the axis label dialog boxes, then click on the tan background.
2. To return the horizontal axis to full scale, click on the Full Scale XY button.
3. To expand the vertical scale (two methods):
- To fill the full y-axis, click on Full Scale Y.
- Enter the plot extremes into the axis label dialog boxes, then click on the tan background.
4. To print the spectrum, pull down the File menu and select Page Setup... Set the Print Background Colors and Images checkbox.

If the cursor stops working for dragging, you have activated the native browser drag and drop mode. Just click the mouse on the tan background and return to the spectrum.
