Table 4-6 Zoom

One way to remember what will happen when you use 

Zoom left

 and 

Zoom right

 

is to remember that the left edge of the display is X=Xmin, and the right edge is 

X=Xmax. In a horizontal zoom, the left edge always remains fixed. The left and 

right keys simply move the current, right edge (X=Xmax) to the left and right, 

respectively.

Description

Zoom

W

The horizontal center line remains fixed, but the window 

contracts vertically. Ymax decreases and Ymin increases in 

such a way that their average remains the same. The graph 

appears to stretch out. If the graph is not centered vertically, 

the graph may drift as well as stretch.

Zoom

X

Like Zoom 

W

, the horizontal center line remains fixed, but 

the view dilates vertically. Ymax increases and Ymin 

decreases in such a way that their average remains the same.  

The graph appears to shrink vertically. Again, if the graph is 

not centered vertically, it may drift as it shrinks as well.

Zoom

Y

Zoom in horizontally

: decreases the time duration represented 

by the window's width. The current tracer position remains 

fixed. Xmin increases and Xmax decreases accordingly. If 

data is streaming, the appearance is that the data stream 

speeds up (increases the "current" of the stream). If streaming 

has stopped, the appearance is a dynamically increasing 

horizontal dilation about the vertical segment X=Xtracer, 

where Xtracer is the x-coordinate of the current tracer location.

Zoom

Z

Zoom out horizontally

: increases the time duration represented 

by the window's width. The current tracer position remains 

fixed. Xmin decreases and Xmax increases accordingly. If 

data is streaming, the appearance is that the data stream 

slows down (decreases the "current" of the stream). If 

streaming has stopped, the appearance is a dynamic 

horizontal contraction of the data with respect to the vertical 

segment X=Xtracer. Once the data stream has contracted to 

the point where it all fits in the display, continuing to zoom in 

contracts with respect to the left edge of the display. Zooming 

out horizontally will eventually stop with data still visible in a 

handful of pixel columns.
