The increase (

INC

) and decrease (

DEC

) plots are types of sequential plots. An increasing plot only

displays points when the X-axis values are increasing. A decreasing plot only displays points when

the X-axis values are decreasing. The increasing and decreasing sequential plots are especially

useful if you are profiling and display depth on the X-axis. Thus the plot shows only the time in

which the sonde is being lowered or raised.

Select

Cross-parameter bins

to set up the number of bins that will appear on the X-axis. This

feature only applies to reports and averaged plots (see descriptions above) with a parameter other

than Date + Time on the X-axis. Changing this value modifies the number of bins into which the

X-axis is divided. The smaller the number of bins, the wider and more general is the plotted

information. The maximum number of allowable bins varies with the capability of your computer

system, and is displayed in parentheses. For example, 100 is selected, and the maximum is 2350 as

shown in the screen above.

Select

Parameters per plot

option to setup the number of parameters that will be plotted together.

If you choose 1, there will be an individual X and Y-axis displayed for each selected parameter.

Select any number of parameters per plot, (from 1 to 4) which provides your data with the best plot

presentation.

There are three scaling options.

Default Scaling

offers fixed limits. These limits correspond to the range of each parameter

as defined by the sensor specifications, so your plot will always fit within these limits.

Manual Scaling

allows you to enter custom limits for each parameter.

The computer scans the data file and determines the limits, then displays those limits on the

plot in

Automatic scaling.

NOTE:

When entering a scaling technique, you need only type the first letter of the desired

technique and press

Enter

. PC6000 will fill in the rest.

Select

Copy automatic to manual

to provide a quick way to copy

from either the default or automatic limits columns to the Manual scaling column.
