# Graphing: Using the Zoom Feature

CPRS graphing's zoom feature provides a way to visually expand areas of interest. To enable this feature for the horizontal axis, select the Zoom, Horizontal check box in the Graph Settings dialog box. To simultaneously expand areas of interest along the vertical axis, select Zoom, Vertical in the Graph Settings dialog box or Vertical Zoom on the right-click menu.

Take the following steps to visually expand (zoom in on) areas of interest:

1. Point to the upper left-hand corner of the area you want to visually expand.

2. Click and hold the left mouse button.

3. Drag the mouse pointer downward and to the right until you have described the entire area of interest.

4. Release the mouse button. CPRS graphing expands the horizontal and (if applicable) vertical axes of all graphs accordingly. In its information bar, CPRS graphing displays the new (zoomed) date range.

5. (Optional) Repeat steps 1-3 as needed to further expand the area of interest.

Reversing the Zoom Process

To instantly return all graphs to their original state:

· Select Reset Display on the right-click menu.

Alternately, you can return all graphs to their original state by taking the following steps:

1. Point to any area on a graph.

2. Click and hold the left mouse button.

3. Drag the mouse pointer upward and to the left.

4. Release the mouse button.

To step backward through the zoom process (reverse the process by increments):

· Select Zoom Back on the right-click menu. (When you've stepped backward through the entire zoom process, this menu selection is unavailable.)
