Scale the Chart

The Process Analyst allows you to change the scale of the data in both the horizontal and vertical direction by dragging the mouse or spinning the mouse wheel.

To scale the data by dragging:

1. Click and hold down the left mouse button on the axis that you want to scale.

2. Drag the mouse in the direction you want to scale:

   • Horizontal axis: drag left to expand the scale, drag right to shrink.

   • Vertical axis: drag up to expand the scale, drag down to shrink.

3. Release the left mouse button to complete the scaling.

To scale by using the mouse wheel:

4. Click the axis that you want to scale.

5. Spin the mouse wheel in the direction you want to scale:

   • Horizontal axis: spin up to shrink the axis, spin down to expand.

   • Vertical axis: spin up to expand the axis, spin down to shrink.

You can disable scrolling in the horizontal direction, the vertical direction, or both by using the Property dialog box or the right-click (context) menu (see Configure Pen Axes).

The Process Analyst indicates whether scaling is enabled or disabled by displaying a different-shaped mouse pointer (see Mouse Pointers).
