Set Axis Min/Max
You may set your own minimum or maximum for each axis by entering the
desired number into the Axis Min/Max text box (the first and last numbers in the
axis. You may also choose the desired Edit Min/Max option from the Options
sub-menu in the Plot menu to move the cursor into the Min/Max text box. Setting
the minimum or maximum automatically “locks” the axis (see below).
A XIS M AXIMUM T EXT B OX
Note: The Min and Max values you specify may not end up being the actual min and max values
used to create the plot. For simplicity, the grid lines on any axis are always multiples of one of
the following numbers: .01, .02, .05, .1, 2, 5, 10, 20, 50, 100, 200, 500, or 1000. The software
will determine the closest possible match to your specified max or min value.
Lock Axis
To lock (or unlock) the axis of a plot, click on the Lock Axis icon for the desired
axis or choose the desired locking option from the Options sub menu in the Plot
menu. Locking the axis will cause subsequent plot spans (when you scroll
through plot spans) to use the same scale as the plot span currently being viewed.
Note: When you move to a date which contains data that falls outside of the plot scale, the software
automatically re-scales so the all of the new data fits on the plot and then locks the scale at
the new settings.

Pause Plot Calculation
You may stop the program from “drawing” a plot at any time by pressing Esc.
The program will stop calculating and drawing the plot as soon as it is possible
and wait for further input before continuing. This feature can be especially useful
on slower machines or larger plot spans when you want to make a change with-
out waiting for the plot to finish drawing.
View Database Information
Double-clicking on any location in a plot will open the Browse window (see
“Using the Browse Window” on page 59) to view the raw data for that time and
date.
